Q2 of 34 Page 7

Sketch the graphs of the following curves on the same scale and the same axes :

y = cos x and y = cos

We observe that the functions y = cos x and y = cos (x/2) are periodic functions with periods π and π.


The values of these functions are tabulated below:



By plotting the above points, we obtain the required curve.
