Integrals

Here we solve few problems of definite integrals. Problem 1:  By the definition of definite integrals, find `int_a^b dx`. Solution: From the definition of definite integrals, we have `int_a^b dx=lim_{h to 0} h sum_{1}^{n} 1, quad` where ` nh=b-a`             `=lim_{h to 0} h (1+1+1+ cdots text{till} n text{-terms})`             `=lim_{h … Read more
