1. The problem statement, all variables and given/known data Find the areas enclosed by the following curves and straight lines: c) y= (1/x2) -1 , y= -1 , x=1/2, and x=2 b) y = x3-1, the axes and y = 26 2. The attempt at a solution Okay I sketched the curve and to me it looks like the curve occupies no area at y=-1 it's undefined there. so isn't the area occupied from x = 1/2 to x =2 so ∫1/x2) -1 . dx y= [(1/x) - x ] + c ( (1/2) - 2) - ( 2 - (1/2)) = -3 but the answer in my book says 3/2 and for the 2nd question The points at which these curves intersect are (3,26) ∫x3 -1 . dx y = (x4/4) - x = 17 1/4 ( x = 0 to 3) ∫26.dx = 26x = 78 sq units( from x 0 to 3) 78- 17/4 = 60 3/4 but in the back of my book it says 60 exactly, and I don't see what I did wrong.. Help is greatly appreciated~!!
