Question

What is the rate of change between the interval x = π and x = three pi over two ?

Answer 1

Give us a chance to consider a capacity y = f(x) Then, dy/dx = f'(x) This f'(x) is the rate of progress.

Hence, in the given interim, the rate of progress = f'(π/2) - f'(π/4). X 1 = π , x 2 = 3 π/2 y 1 = - 1, y 2 = 2.
