Show all steps in the solutions to the following problems. Insufficient justification will result in a loss of marks. You will not need Maple for today's lab. 1. [4 marks] Determine each of the following. Show all of your work. ( a ) ar (sin (3) 2t at 2. (5 marks] Suppose y = / V z - ldt. (a) Use a property of definite integrals and FTOC Part 1 to find y'. (b) Use FTOC Part 2 to evaluate . V1 + ly'dx.
