Logarithms II

Posted by ricardogm on October 10th, 2017

Hi

Today we are going to work mostly about logarithms:

1. Send me an email telling me the origin of  “logarithms” and some uses of them in real life.

2. Now we are going to use geogebra to create some models about the typical situations related to exponential grown and decay. Pay attention and send me the geogebra files you are going to make: one for compound interest and another for depreciation.

3. Solve these problems in your notebook:

Percentages, compound interest, Logarithms

Posted by ricardogm on October 5th, 2017

1. A thorough explanation of Compound interest.


Try to solve the questions at the end of the page.

2. Two practical cases. Solve them in your notebook:

1. Interest:
Marisa invests $300 at a bank that offers 5% compounded annually.

a.) What is the growth factor for the investment?

b.) Write an equation to model the growth of the investment.

c.) How many years will it take for the initial investment to double? And to be $1000?

2. Depreciation:
Matt bought a new car at a cost of $25,000. The car depreciates approximately 15% of its value each year.

a.) What is the decay factor for the value of this car?

b.) Write an equation to model the decay value of this car.

c.) What will the car be worth in 10 years?

d.) When will the car be worth $100?

Well, some questions need this:

Yes, it’s time for a new operation: logarithms.

Radicals

Posted by ricardogm on September 28th, 2017

 

1. First of all, I’m gonna show you some interesting tools (Symbolab, for example). Pay attention and use it to correct the exercises from yesterday.

1.1 5 minutes of mental calculations, using “10 seconds of math”.

2. A little theory. Read this page and solve the questions at the end.

3. Some exercises.

4. Exercises 3 and 4 from here. Solve them in your notebook and correct them with Symbolab.

Números reales… por ahora

Posted by ricardogm on September 24th, 2017

Muy buenas

Primer día de práctica en la sala 011 y vamos a aprovecharlo para conocer alguno de los recursos que utilizaremos durante el curso:

0.  Para empezar un mini trabajo de investigación. Investiga el origen de los logaritmos, para qué se desarrollaron y quién fue responsable, y cómo se calculaban antes de tener calculadoras. Todo ello en menos de 100 palabra. Envíame al mail ese trabajo. IMPORTANTE: usa la dirección de correo que vayas a usar durante el curso, y pon en el asunto tu nombre (o nombres, si sois dos).

1. Seguimos con unos cuantos ejercicios interactivos de Vitutor. Concretamente, le echaremos un vistazo al apartado 1 de la teoría y haremos los ejercicios del 3.1.4 al 3.1.6. Después, del 3.1.9 al 3.1.14, y terminaremos con el 3.1.17.

2. Os voy a presentar unas cuantas herramientas útiles para corregir los miles de ejercicios que haréis  entre este curso y el que viene. Se llaman SymbolabWolframAlpha y Wiris, y están en el menú lateral, en el apartado de C.A.S. Úsalas para corregir alguno de los ejercicios de estos días (por ejemplo, alguno de valor absoluto, radicales, etc.).

3. Por último os enlazo las actividades sobre radicales que ya hemos trabajado en clase. Haz la 10, en tu cuaderno, y corrígela con la ayuda de alguno de esos programas.

Sets of numbers

Posted by ricardogm on September 17th, 2017

Hi

First day in the computers room.

Let’s start with a little history:

1. Try to find out in the internet the name of the man who proved the existence of irrational numbers. Send me an email with this story. Use the email that you are going to use for all the year. You will have to send me lots of work in the following months.

1. Open this worksheet, read it (is about converting decimals into fractions) and solve the exercises in your notebook. Check the answers with the calculator.

2. Now you can do some exercises about intervals.

3. And some more.

4. These are the exercises we did in the classroom. Finish them.

5. Here you have a complete unit about real numbers.
A little video about sets of numbers. We are going to listen to a part of it, and take notes.

Now another one about intervals:

For you curiosity, here are the first 1000000 decimals of piAnd time to start with radicals.
