1− x2 dx Solution: The circle has the equation x2 +y2 = 1. Solving for y gives y = √ 1−x2. 3) T F If the graph of the function f(x) = x2 is rotated around the interval [0,1] we obtain a solid with volume R1 0 πx 4 dx. Solution: Yes, the cross section area is A(x) = πx4. Integrate this from 0 to 1. 4) T F The function f(x) = ex is the ...

Now, in this example, because u = x + 4 it follows immediately that du dx = 1 and so du = dx. So, substituting both for x+4 and for dx in Equation (1) we have Z (x+4)5 dx = Z u5du The resulting integral can be evaluated immediately to give u6 6 +c. We can revert to an expression involving the original variable x by recalling that u = x+4 ...

In fact, if 0 < x1 < x2 < ··· < xn−1 < 1 is a partition of [0,1], then sup [0,x1] f = ∞, so the upper Riemann sums of f are not well-defined.
