Evaluating definite integrals using limits

WebSal wants us to evaluate the definite integral of (9-x^2)^1/2 from -3 to 3. Instead he simply manipulates the function y= (9-x^2)^1/2 dx, takes the square of both sides and simply forgets the dx. I thought to calculate the definite integral of a function we first had to determine the function derived from and then use our interval values while ... WebDec 9, 2011 · For the original definite integral, the bounds are for the variable x. When you change variables from x to u, you typically change the bounds to be in terms of the new variable. If you want, you can substitute back and should get the same answer. u 3 3 = cos 3 2 x 3. Now using the original bounds for x:
