Histograms, Graphs and Functions Exercises

Welcome to the exercises of the Histograms, Graphs and Functions learning module!

A macro to build a histogram

Create a macro which builds and draws a histogram with the following features:

The number of bins is 64 and the x axis ranges from 0 to 16.
It is filled with random numbers distributed according to a linear function (pol1).
Its line width is thicker than the default one.

A macro to build a graph

Create a macro which builds and draws a graph with the following features:

The title of the plot is My graph.
The x and y axis have labels my_{X} and myY respectively.
The points are three and with these coordinates (1,0), (2,3), (3,4).
The marker is a full square. Its coulour is red.
A line joins the points and is orange.

A macro to build a function

Create a macro that follows these steps:

Create a function with formula cos(x) and draw it.
Create another function which adds a parameter to cos(x).
Set a value for the parameter.
Change the color of the line of the second function.
Draw the second function in the same canvas as the first one.
