(3 pts) 5a) Your friend is trying to do the integral 2r + 3 12 + 3.x + 2 They groan "Oh no, not another partial fractions problem, these are so long!" Does your friend have to use partial fractions for this integral though? What other (possibly shorter) method could you recommend they try? 2x + 3 (3 pts) 5b) Use your alternate method from part (a) to find x2 + 3x + 2 (6 pts) 6) Evaluate the integral / x cos(2x)dx
