Question

Give the number of values of c that verify the mean value theorem for f sin ( x x ) = ( ) on the
interval PLEASE SEE 8. http://www.math.uh.edu/~pamb/1431EMCF%2018.pdf

Answer 1

I am stuck at \[\frac{2\sqrt{2} }{ 3\pi}\]=0

Answer 2

f'(c)=(f(b)-f(a))/(b-a)

Answer 3

cos(c)=0, a<c<b
c = pi/2 or -pi/2
