If f is integrable on [a, b], the following equation is correct. f (x) dx = lim > f (x;) Ax, where A.x = - b - a and x; = a tix. n i=1 Use the given form of the definition to evaluate the integral. (1- x2 ) dxEvaluate the integral by interpreting it in terms of areas. 20 f |x 10| dx 0 If f is integrable on [a, b], the following equation is correct. f (x) dx = lim f (x;) A., where Ar = b - and r; = a tix. i=1 n Use the given form of the definition to evaluate the integral
