(c) It turns out that you cannot express that integral in terms of functions you learned so far. So our best bet is to approximate it using Riemann sums. First, let's try to understand the function we are integrating. Find the derivative of the function f(t) =te* and decide whether this function is increasing or decreasing on the interval [1, 2]. (d) Use your answer in (b) to find the worst overestimate and the worst underestimate for our integral I using 6 rectangles of equal base length. What is the average between the worst overestimate and the worst underestimate?
