We will compute the definite integral using the equality f(x)dx = lim f(I.) Ax i-1 where ; are right-hand endpoints of the subintervals. (a) Imagine chopping the interval [-1, 5] into n equally sized subintervals. Ax is the length of each of these subintervals. ; is the right-endpoint of the ith subinterval. Determine Ax and x;. Ax = 6 This answer should be a function of n. Ci -1+6i This answer should be a function of n and 2. When 2 = n, you should have , - 5, the right-endpoint of our interval. (b) Using the answers you found above, compute for f() = 3 + 3x using the sum formulas found on page 218. This answer should be a function of n
