MATLAB Plotting Trigonometric Functions

Type at the Matlab prompt:

x=[0:0.1: 2*pi];

y=sin(x);

plot(x,y);

xlabel(`angle (rad)`)

ylabel(`sine`)

title(`y = sin(x)`)

You will see a sinusoid on the graphics window. The sinusoid is plotted for values of x between 0 and 2 p; the step between consecutive values of x is 0.1.

Experiment with commands "cos", "tan", "cot".
