The area of the function f(x) is right but the interval is wrong. Help.
5.1: Problem 2 Previous Problem List Next (1 point) The area A of the region S that lies the sum of the areas of approximating rectangles: under the graph of the continuous function f on the interval [a, b] is the limit of = lim b-a where Ax = and xi = a + iar. The expression 4n -1 on the interval (0,pi/4) gives the area of the function f(x)- tanx Note: You can earn partial credit on this problem. Finally, we take the limit as n tends to oo to obtain the eract area under the curve:
