1. The problem statement, all variables and given/known data Find the area of the curve 2/sqrt(x) bounded by x = 0, y = 3, y = 1 2. Relevant equations The textbook claims the answer is 3. 3. The attempt at a solution I tried both vertical and horizontal elements, but got different answers than 3. Here's my attempt at vertical elements: since y = 1 is the farthest right value of x, I solve 1 = 2/sqrt(x) for X to find x upper, which is 4. Now I form my integral: integral(4-0) of 2/sqrt(x) (dx) Integrate: 4 * sqrt(x) Solve the definite integral: (4 * sqrt(4)) - (4 * sqrt(0)) = 8 What have I done wrong?
