Sketch the graphs of the following pairs of functions on the same axes :
f(x) = sin 2x, g(x) = 2 sin x
We observe that the functions f(x) = sin 2x and g (x) = 2 sin x are periodic functions with periods π and π.
The values of these functions are tabulated below:
Values of f (x) = sin (2x) in [0, π]
Values of g (x) = 2 sin x in [0, π]
By plotting the above points, we obtain the required curve.
