Q. 2 A

# Sketch the graphs of the following pairs of functions on the same axes :f(x) = sin x, g(x) = sin We observe that the functions f(x) = sin x and g (x) = sin (x + π/4) are periodic functions with periods 2π and 7π/4.

The values of these functions are tabulated below:

Values of f (x) = sin x in [0, 2π] Values of g (x) = sin (x + π/4) in [0, 7π/4] By plotting the above points, we obtain the required curve. Rate this question :
