Definite integrals

Question

Find the definite integral of ∫₁² 3t² + 2e^3t + 1/t + 2 cos 3t + cosht dt

Answer 1

OK...then the integral is simply the sum of the integrals of all the terms evaluated between 1 and 2.

The first 2 terms are easy.

The integral of the third term is ln t.

The derivative of sin is cos...that hint should get you the 4th term

and the derivative of sinh is cosh.

Have at it!
