Use the definition of the definite integral by finding Ax = b-a n and partition a = Xo

Use the definition of the definite integral by finding nx a = XO < Xl < < < xn-I < xn = b to find an expression for the area under the graph of f (x) as a limit lim Do not evaluate the limit. n + 00 (b) f (x) = cos(x), 1 S x 6 and partition
