Applying the power rule for integration, d n+xn+, where n n represents a number or constant function, in this case n 1. In this section we will look at integrals with infinite intervals of integration and integrals with discontinuous integrands in this section. The definite integral of x is used when the integration has to be performed between two specified limits. Hence, ∫sec3dx = 1 2secxtanx + 1 2ln|secx +tanx|+ C. Using the product rule the value of the integral of x can be determined by taking f(x) = x and g(x) = 1. 1. ∫b af(x)dx = lim n → ∞ n ∑ i = 1f(x ∗ i)Δx, provided the limit exists.
