Math Help Please
State two intervals in which the function y = 7 sin (1/5x) +2 has an average rate of change that is
a) zero
b) a negative value
c) a positive value
State two points where the function y= 1/4 cos(4(pi)x) - 3 has an instantaneous rate of change that is
a) zero
b) a negative value
c) a positive value
Any help is appreciated, thanks !

You don't really restrict the domain of a sine curve, right? I mean, it DOES go from 0 degrees onward. I'm only in Calc AB, but I'm pretty sure that's how it works.
Don't you mean restrict the [i]range[/i] of the sine curve to its respective amplitude?
Thanks for the explanations!
