no. 2 only please detailed solution

1. Evaluate tan |2x) dx (5 points) 2. Let R be the region below enclosed by the curves x = 2 - y?, y = - sin ( ), and T = -1, as shown below. Set up (and do not simplify) the (sum of) definite integral(s) equal to the following quantities. (-1, V3) 2 1 (-1, 1) R -1 -1. (1, -1) (a) Area of R using vertical rectangles (3 points) (b) Volume of the solid generated when R is revolved about the line r = 2 using the method of washers (4 points)
