Find the derivative function F'(x) of the function F(x) defined by: cos- (x) F(x) = cosh (t) . sinh (t)dt F' (x ) = Note. Here is a list of functions you may use: x^n, x^(1), exx log(x) (base is e) sin(x), cos(x), tan(x) sinh (x), cosh(x), tanh(x) asin(x), acos(x), atan(x) asinh(x), acosh(x), atanh(x)
