Consider the sum In(2.25) · 0.25 + In(2.5) · 0.25 + In(2.75) · 0.25 + In(3) · 0.25 + In(3.25) · 0.25 + ln(3.5) · 0.25 Express the sum above using summation notation. The only variable in your result should be the index variable i. |This sum can be viewed as a right endpoint approximation for the area under the curve of some function f(x) between a and b. With this perspective, what are Ax, a, b, and f (x)? Explain.
