Question

What is the average rate of change of the function y = 3 cos x on the interval [π/2, π]?

Answer 1

Answer:

¹

Step-by-step explanation:

Average Rate of Change is

ts

$\frac{f(b) - f(a)}{b - a}$

Here b is pi, a is pi/2,

$\cos(\pi) = - 1$

$\cos( \frac{\pi}{2} ) = 0$

So we have

$\frac{ - 1 - 0}{ \frac{\pi}{2} } = \frac{ - 1}{ \frac{\pi}{2} }$

Answer 2

Answer:

-2/pi
