@jlhurwit75
use the formula for newton method
X,n+1 = X,n -  f(x)/f'(x),  start with n=0 so that 
X,1= X,0 - f(X0)/f'(x0)  say X,o=3, then also try X,o =1
you might get a max of +pi, etc

note this is an iterative process and do them successively for the approximation of roots

yea i know that, I don't have a calculator with me and when I try to do it with mathmatica it doesnt work for this specific problem, I dont know the program well enough to know what I'm doing wrong
