what is the answer to this question?

Use the substitution t = tan N X to transform the integrand into a rational function of t and then evaluate the integral. (Remember to use absolute values where appropriate. Use C for the constant of integration.) 6 dx 3 sin(x) - 4 cos(x) 6 3 in / 4 tan ( 2 ) - 1 ) - intan ( 2 ) + 4 + c X
