I need help with the questions in the picture. Please let me know if there is any question

1. Find (a) S(5x' + + )dx (b) J dx 2+x (4 marks) 2. Find f(x), given that f (x) = (x + 2)" is the derivative of f(x) and (-1,2) lies on f(x). (3 marks) 3. The diagram shows part of the curve y = sinx. The shaded region is bounded by the curve and the lines y = 0 and x = = 4 Given that sin- 31 2 and cos- 31t _ V2 4 2 4 2 calculate the exact area of the shaded region. (6 marks)
