i have got the derivative and equated to zero but after that i got stuck i cant get a numerical number
-
When you equate the derivative to zero you get : X = TanX
This is not easy to solve for X, and I have resolve to use the iterative method of Newton-Raphson, that I keep a programme for. The solution for X turned out to be a very small number close to zero.
X = 0.00001594968
No wonder you are stuck !!!
