The average rate of change of cot(t) 2017-01-18
Brianna pose la question :
Hello! It's been a while since I've taken a math course, and I'm stuck on a problem in my calculus course.
The question is this:

Find the average rate of change of the function over the given interval.
h(t)=cot(t) a) [5pi/4, 7pi/4]

Kenneth pose la question :
Hello:

How is the average determined for the following amount if it earns compound interest?

Here are my calculations, but I'm not certain that they are correct: Initial amount invested $500.00:

$500.00 @ 5% = $525.00.

$525.00 @ -2% = $514.50.

$14.50/$500.00 = 2.9% divided by 2 equals an average of 1.45%.

If this average, 1.45%, is correct, how can I use 5% and -2% to determine the same average? Is it possible?

I thank you for your reply.

Tammy pose la question :
Suppose that the average rate of change of a function f over the interval from x=3 to x=3+h is given by 5e^h-4cos(2h). what is f'(3)? I would appreciate any help with this question.
