Tutorial 3 - MAT 1332A - September 28, 2009•Integration by substitution and by parts (at the same time)1.∫sin√xdx•Integrals and areas1. Sketch the region bounded byy=ex, bounded below byy=xandon the side byx= 0 andx= 1. Then find the area of this region.2. Do the same for the region enclosed by the parabolasy=x2andy= 2x-x2. Explain how to sketch the graphs of the parabolas andhow to find their intersection point.
