Can someone work these problems out? I want to see if I got the correct answers and if I didn't, be able to see where I went wrong.

1. Evaluate each of the following indefinite integrals. . a) xVI-r dx . b) sec? (0) tan' (0) de . c xx +2 dx dt . d) cos? (t) 1 + tan(t) . e) / sec (x) tan(x) dx 2. Evaluate each of the following definite integrals. a) cos( # ) dt 0 -13 o b) o V(1 + 2x)2 4 D C) 1+ 2x o d) cos(r ) sin(sin(r) ) dx 0
