examen feo :(

Bueno, estamos ya en examenes del 3er parcial, de hecho ya vamos de salida... hoy hice el de mate y me fue muuuy feo, nada mas espero q no sea TAN feo.. =[ pero pues como sea, en el final voy a hecharle ganas para reponerme =) la verdad es que este a sido un parcial muy pesado! lo unico bueno fue semana santa, pero antes estuvimos con lo de "murder" que nos tuvo un muy buen rato en vueltas y problemillas técnicos, que nunca faltan (casualmente nunca me faltan), pero fue algo divertido, hasta eso jaja... bueno, lueego ya examenes, que trabajos parciales a morir, que tareas en exceso, y que un tal mago! en fin, todavia no me repongo de las desveladas constantes, que también son motivo de mi rendimiento, ya pues, de maate... espero mejorar porque no domino los temas, apenas y tengo una idea de como son jaja, asi que ya me voy a poner las pilas =)

hasta la proxima :**

bloggie =]

Hi bloggers =) I am still working with my team on the murder we wrote project! the new subject of the class is a little bit difficult, I should study since now.. jeje

well... I will write again when I have something else to say or when we finish our project =)

bye bye

primavera!!

Hi bloggers =) It has been a long time since the last update!
Today I am going to talk about the last few weeks, first, CENEVAL, it was awful! I think the easiest part was spanish and maths, but everything was very confusing, specially the part of international overview or whatever... I hope to have a good grade, because it will affect in every subject! After the exam, it was a great weekend! long =D! Someone once said that there is always a rainbow hiding behind a storm, and it was the case! hehe
About our project of Murder We Wrote... we are running out of time! it is very close and we have to start NOW! we already have the idea of the movie =) well.. I don't have much to say, so...
bye bye =)

gant graph ;)

This is our project's schedule, I hope we can actually follow it step by step, because time is running... the day after tomorrow is the partial exam!

I hope have a good grade!

1. What is the Newton’s Law of Cooling?

It says that the temperature of a body changes with a rate relative to the temperature of its surroundings or environment.

2. What variables in your problem correspond with the variables in the Newton’s Law of Cooling?

The body was found à T= 9:10 PM º = 96 degrees

T= 9:16 PM º = 95 degrees

T= 0 º = 101 degrees (but was possible illed)

Library’s temperature à T= 8:00 PM º = 75 degrees

T= 9:00 PM º= 70 degrees

3. According to this Law, at what time approximately the death happened?
4. How does the room temperature affect the time of death?

As we know, the Newton’s law of cooling compares the temperature of the body with the one of the room or environment, so it depends on the different temperatures of the room at different times to determine the time of death.

5. How does an illness (e.g. fever) affect the time of death?

It affects because the temperature of the body before being killed is unknown, and it would be uncertain to give a “possible temperature” because having the equations done, the time will be different by seconds or minutes, which will affect the results.

6. How exact is the approximation of the Newton’s Law of Cooling for predicting the time of death?

It depends on the environment in which the body is, and the health of the body as well, if the environment’s temperature is constantly changing, it is harder to get an exact result and if the body has fever is the same (question 4&5), but the answer would be aprroximated indeed.

Murder We Wrote 2nd =)

Questions:


4. What methods are commonly used to find the time of death?

*The rate method: it measures the changes on the body comparing it with one known initial or final rate, for example the changes of temperature of the body.
*The concurrence method: it compares something that happened in the crime with something known that happened to the victim before the crime, for example the last known meal.
*By the living animals in the body (larvas/bugs), it is usually used when the body has been outside (not on a closed place) for a reasonable time.
*Algor Mortis
* cooling law of newton: is about what we are learning on class, the temperature of the body is compared with the environmental temperature.

5. What factors are considered in Algor Mortis?
1. The "size" of the body.
2. Clothing and coverings.
3. Movement and humidity of the air.
4. Immersion in water.

*temperature and external factors.

6. How does the environment affect the time of death?

by the larvae living on the corpse, if the body is exposed to a open environment, there is more chance for the body to grow larvae and that's how forensic scientists according to the size of the larvae can tell how many time has been there, another things is the clothes of the body because it changes the temperature, also the water or humidity, for example, if it rains it is difficult to tell the time of death of the body.

7. What can you tell about the different methods of temperature reading of the body? Do they make a difference in the results?

Of course they make a difference, and all of them are very useful because if there are suspects, it is possible to know who was the murderer or at least tell if they are telling the truth, mostly by the method of the cooling law of newton, besides it also helps to know if what the witnesses say is true, if some witness is lying about when they saw the body or the murderer too.

All methods are useful to solve crimes

topss =)

me quedó 90 =) nose que decir de la semana en mate, nomas que fue: estudiar, examen, incertidumbre, descanso... ya me voy rápido porque sino la pag se enoja conmigo y no me deja subir jaja luego le agrego algo y lo pongo bonito =)

el prox parcial le voy a hechar más ganas =D
bye :**

mañanaa exameeeen...!!!

Murder We Wrote ;)!

Team’s name: Los Topis

Integrants:

• Topacio Campos Muñoz
• Yuliana Sáchez Camporredondo
• Aitza Terán Roldán
• Armando Amor González

Roles "Murder We Wrote":
The Math Expert: Yuliana
The Media Expert: Armando
The Journalist: Topacio
The Forensic Scientist: Aitza

Questions:

1. What is forensic science?

Is the application of science to solve crimes and answer questions of interest to civil law.

2. What kind of evidence can be collected in a murder case?

Fingerprints, footprints, time of death, DNA, toothmarks, physical evidence, etc

3. Why is important to determine the time of death?

Because knowing the time of death allows the investigator to determine if the possible murderer/ suspect is guilty or not, or together with the other evidences to determine who the murderer was. Time of death can be determined by the body’s temperature, muscles hardening or the insects living in the corpse.

4. Write a short paragraph about what you think is the GOAL or MAIN objective of the final project.

We think that this project “Murder we Wrote” seeks to motivate us, as students to learn more about the applications of mathemathics and how it can be related to other areas of study such as biology or forensic science among others; to notice that there’s plenty of maths out there and we can actually be part of them if we like. And it can be very interesting and funny indeed.

Bueeeno.. ahí esta la info del equipo de mate =)

(8) Queen - Don`t Stop Me Now ;)

quiz feo x(

Me fue mal en el quiz de hooy x( nose por qué me pasa eso si si entiendo en las tareas y actividades! y a la hora de hacer el quiz nomas me bloqueo, y eso que nunca me pasa eso en los exámenes, sólo en el final del semestre pasado que estaba bien desvelada por hacer la maqueta de física y ni tiempo de repasar nada jajaja... a puees y en el quiz lo que sospecho que me pasó es que no suelo usar la "u", nomas pongo las cosas asi como son... y a la hora de q me dieron las identidades cuadradas ya me quede :| asi que nota personal: usar u y du, dominar algrebra... en fin, es el 1er parcial...me puedo recuperar =D

Toppy =)

Esta semana seguimos viendo derivadas, me gustan :D jaja aunque me fue mal en el quiz x( pero ya le entendí bien a todo... bueno, el lunes veremos como me va en el próximo, y ya empiezan examenes también... así que ahí es donde tengo que demostrar lo que se. Linda nos dijo el otro dia que si nos va mal es más por el algebra que por el cálculo integral, y tiene muuucha razón, yo la verdad tengo en blanco algebra! de hecho por eso me fue mal en el quiz, y pues cálculo, mínimo en donde vamos, no esta tan complicado, será que ya vimos demasiaaadas derivadas en nuestras vidas jajaja bueeno... sin nada más que decir me vooy ;*

otra ;)

Bueno jaja, esta segunda entrada es porque en la primera olvidé responder las primeras preguntas del blog...


Our lives begin to end the day we become silent about things that matter.
- Martin Luther King, Jr.

I think this activity starts with this quote because a very important aspect of human beings is the strong need of communication we were born with, in fact we cannot live without it. A blog is made to express our feeling or thoughts about something, which people can read and leave messages if they want to, in this subject we are using blogs to talk about calculus, what we like, what we don't understand, etc, therefore the teacher can know how we are doing with the topics and stuff. Anyway, coming back to the phrase, it is quite true what it says, because if we don't express or talk about those things that make life important, its like if we just stop living them. Besides, learning and teaching is what makes life worthy, that's why I liked the quote =)

I will be using this blog every time I learn something new in math class, even if I learn something new about anything I might write it here, since I already have a blog I'll use it whenever I feel like it =), well surely I'll write every week or more, and I will also leave comments to my classmates. This blog might be very useful =)

no puedo poner foto :( luego intentaré de nuevo

Eso es todo jaja hasta la próxima ;)

10000 and 1

Yo,

hice este blog para la materia de cálculo integral y lo más probable es que actualize cada semana, si me va bien...a nadie le caen mal unos cuantos puntos extras en el final ¿o no?... Soy Topacio Campos Muñoz, estudio en la prepa del tec, mi último semestre, y talvez mi única lectora sea Linda Licón (mi maestra de mate, aunque siendo así, ella sabe) puesto que ella es el porqué de este espacio.

En fin, Linda nos pide que en este primer "post" hablemos de algo que hayamos aprendido durante la semana y he aquí:

***********************************************************************************
Los primeros temas del parcial se me fueron en blanco he de admitir, si acaso la última tarea, de la cúpula, la ventana y las probabilidades de error (creo), después de una buena explicación, me gustó, pero no aseguro poder resolver uno diferente si me lo ponen; ahora lo nuevo es: las derivadas al revés, y más me vale que me vaya bien =)
dejo aquí una foto de mi primer dia de clases, y como he aguantado hahaha

esta padre esto jaja :D haber que pongo luego, [TE] todo por hoy :**
