Q1

Approximate the area under the curve over the specified interval by using the indicated number of subintervals (or rectangles) and evaluating the function at the right-hand endpoints of the subintervals. (See Example 1.) f(x) = 49 - x2 from x = 1 to x = 7; 4 subintervalsEvaluate the definite integral. 5 3 7 x2 dx 0\fEvaluate the definite integral. 12 dx\fEvaluate the definite integral. 5 15 2 dy 1\fEvaluate the definite integral. 2 167 -3 dz 1Evaluate the definite integral. -1 56w-2 dw -4Evaluate the definite integral. 2 - 3 8x + 8x) dx 0
