As we have learnt in

y=f(x)  → |y| = f(x)

y = f(x) is given

  1. Remove the part of the graph which lies below x-axis

  2. Plot the remaining part 

  3. take the mirror image of the portion that lies above x-axis about the x-axis.


 

First draw y = cos x

Then,

  1. Remove the part of the graph which lies below x-axis

  2. Plot the remaining part 

  3. take the mirror image of the portion that lies above x-axis about the x-axis
