+ A function on the real line could use a completely different value of C on either side of the origin as in: The following function has a non-integrable singularity at 0 for a ≤ −1: Let f be a function which has at most one root on each interval on which it is defined, and g an antiderivative of f that is zero at each root of f (such an antiderivative exists if and only if the condition on f is satisfied), then. there is a singularity at 0 and the antiderivative becomes infinite there. But it is often used to find the area underneath the graph of a function like this: The integral of many functions are well known, and there are useful rules to work out the integral of more complicated functions, many of which are shown here. If the integration is done in the complex plane the result depends on the path around the origin, in this case the singularity contributes −iπ when using a path above the origin and iπ for a path below the origin. Integration is the reverse process of differentiation, so the table of basic integrals follows from the table of derivatives. You’ll find that there are many ways to solve an integration problem in calculus. The list of integral formulas are ∫ 1 dx = x + C ∫ a dx = ax+ C ∫ x n dx = ((x n+1)/(n+1))+C ; n≠1 ∫ sin x dx = – cos x + C This article is a list of standard integrals, i.e. If both exponents are even, use the identities sin2(x) = 1 2 1 2 cos(2x) and cos2(x) = 1 2 + 1 2 cos(2x) to rewrite the integral in terms of powers Partial derivative; Disk integration; Gabriel's horn; Jacobian matrix; Hessian matrix; Curvature; Green's theorem; Divergence theorem; Stokes' theorem; Series. u d v = u v-? a An indefinite integral is a function that takes the antiderivative of another function. Note: x > 0 is assumed throughout this article, and the constant of integration is omitted for simplicity. Use double angle formulas to find the antiderivatives. , If we know F(x) is the integral of f(x), then f(x) is the derivative of F(x). Therefore, the desired function is f(x)=1 4 {\displaystyle ax\in \left(n\pi -{\frac {\pi }{2}},n\pi +{\frac {\pi }{2}}\right)} n This technique works when the integrand is close to a simple backward derivative. Z dx a 2+x = 1 a tan 1 x a +C 9. sec2 xdx= tanx+C 10. π For having a continuous antiderivative, one has thus to add a well chosen step function. The indefinite integral is related to the definite integral, but the two are not the same. {\displaystyle ax\in \left(n\pi ,n\pi +\pi \right)} Z cosxdx= sinx+C 6. Other useful resources include Abramowitz and Stegun and the Bateman Manuscript Project. , A simple example of a function without a closed form antiderivative is e−x2, whose antiderivative is (up to constants) the error function.
