Question

Estimate the area under the graph of f(x) = 3 cos(x) from x 0 tox = 7/2 using four approximating
rectangles and right endpoints. Is your estimate an underestimate or an overestimate?
Step 1
Rectangle areas are found by calculating height x width.
The width of each rectangle equals Ax and the height of each rectangle is given by the function value at the
right-hand side of the rectangle.
So we must calculate R =) f(x,)Ax = [f(x1) + f(x,) + f(x3) + f(x4)] Ax, where X1, X2, X3, X4 represent
j = 1
the right-hand endpoints of four equal sub-intervals of
0,
Since we wish to estimate the area over the interval
0,
using 4 rectangles of equal widths, then each
rectangle will have width Ax =
