1/2 of sin(2x)
All it means to take the second derivative is to take the derivative of a function twice. For example, say you start with the function y=x2+2x The first derivative would be 2x+2 But when you take the derivative the first derivative you get the second derivative which would be 2
x can go to + or - infinity. f(x) is limited from + 1/2 to - 1/2.
(x+sinxcosx)/2, can do it by parts or by knowing your double angle formulas
Take the derivative of the function.
