Posted by ricardogm on March 22nd, 2017

Hi

Some exercises from vitutor.com to do before the exam. You should solve them FIRST in your NOTEBOOK, and correct them with the computer (but who am I to give you advice?).

1. Vectors: (Solve the sections anotated in parenthesis):

3.1.1.Vector posición (1-3, 7-8)

3.1.2.Módulo. Distancia (1-4)

3.1.4.Operaciones con vectores (2-4, 9-12, 13-14)

3.1.5.Punto medio (1-4)

3.1.6.Puntos alineados(1-4)

3.1.7.Punto simétrico (1-4)

2. Lines:

3.1.1. Ecuación recta I (1-5)

3.1.4. Paralelas ejes (1-4)

3.1.5. Rectas paralelas (1)

3. Functions:

3.1.1.Función (10-13)

3.1.2.Dominio (1-5)

3.1.3.Recorrido (1-5)

3.1.4.Puntos de una función (11)

3.1.5.Representación gráfica (7-10)

3.1.7.Crecimiento y decrecimiento (1-6)

Average rate of change and piecewise functions

Posted by ricardogm on March 15th, 2017

Hi

1. Use Geogebra to solve exercises 27, 28 and 29 from this worksheet. Send me the files.

2. We are going to use Geogebra to plot piecewise functions. Pay attention and send me the file.

 Hi

This is the worksheet.

And an applet about domain:

Exercises from p. 49-50 of this book.

Functions I, domain

Posted by ricardogm on March 1st, 2017

Hi

We are starting with functions today:

1. Read this page and send me an email with the most important things you see there. You should find what a function is, what rules it has and what domain means, at least.

2. Open this Geogebra applets with a simple example of a function.

Now, play with them and try to answer these questions:

a) What does f(3) mean?  How much is it? How can you calculate that?

b) Are there more than one value of a with the same value of f(a)? Is that possible in a function?

Send me the answers.

3. Now we are going to create something similar. Pay attention and send me the file.

4. Read pages 40 and 41 of this book . They show you how to calculate the domain of a function.

5. With this information, solve these exercises:

domain.pdf

6. More exercises.

You can find the same exercises with solutions in this link.

Midpoints, lines etc.

Posted by ricardogm on February 15th, 2017

Hi

Time to work with Geogebra. Pay attention and send me the files, as usual.

1. The first one is about midpoints.

2. The second about symmetric points.

3. The third one about lines.

4. Now go to this page, read everything, take notes and solve the questions.

5. The same with this page.
