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]Answered by Penny Nom.     Interest rate over two periods 2009-04-12 From Kenneth: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.Answered by Penny Nom.

The average rate of change of a function 1999-04-20 From Tammy: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. Answered by Harley Weston.
