1) In a regular polygon the difference between the interior angles of a (n-1)sided polygon & (n+1)sided polygon is 9. find n? 2) In a regular polygon the difference between the exterior angles of a (n-1)sided polygon & (n+2)sided polygon is 6. find n?

The functions are f(x)= lnx, x>0 and g(x)=sinx. Let H be the composition of f with g, or H(x)=f(g(x)) and A) Find the domain of H B) Find the range of H C) Find the zeros of H

I have to find the relative minimum and relative maximum of g'(x)=(x+1)(x-1)^2(x-2). What I've done so far is constructed a sign chart using the critical numbers, but I'm confused. To the left of -1 it's +, to the right of -1 it's -, to the left of 1 it's...

This problem is really weird. I have to explain why MVT applies for f(x)=2sinx-sin2x on the closed interval 7pi,8pi and then determine all values of c in the interval (7pi,8pi) that satisfies the conclusion of the theorem. However, the condition of MVT is...

Thanks. That helped clear it up, because I wasn't sure what the squared would do. Also, a similar function of h''(x)=(x-1)(x+1)^2(x+2) asks what values of x h''(x) concaves up or down for, and like the other problem, I made a sign chart and got the same c...

I see. I thought it was -pi to 3pi because the period was 2pi when I was inputting the domain and range.

So to reiterate, the values of c that satisfy the conclusion of the theorem are 15pi/2 and 17pi/2?
