Calculate the average rate of change of the function from
θ = π/10 to θ = π/8.
(Round your answer to two decimal places.)
f(θ) = 9 sin(9θ)
Answered by Steve
the average rate of change is just

f(π/8)-f(π/10)
-------------------
(π/8 - π/10)

Now just plug and chug. It's just the slope of the line joining the two points on the curve.
