Given Rn = g: 1'21 9 4 4 (3 + i?) cos (3 + i;)] , express the limit as n > 00 as a definite integral, that b is provide a, b and an) in the expression f f(m)dm. a \"Swamp Evaluate the integral by interpreting it in terms of areas. In other words, draw a picture of the region the integral represents, and find the area using geometry. 9 f |2a3 6|da: 0 4 NO 4 To find the blue shaded area above, we would calculate: f(x)dx = area a Where: a = b = f (ac) = area
