# Evaluate the following integrals as a limit of sums:  Formula used: where, Here, a = 0 and b = 2

Therefore,  Let, Here, f(x) = x2 + 1 and a = 0  Now, By putting x = 0 in f(x) we get,

f(0) = 02 + 1 = 0 + 1 = 1

Similarly, f(h) = h2 + 1  In this series, 1 is getting added n times Now take h2 common in remaining series   Put, Since,              Rate this question :
