Integration Formula 1x
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.
Integration formula 1x. Cos x dx sin x c. The answer is that fx1x on mathbbr implies that there are constants c1c2inmathbbr such that fxlogxc1 for all x0 and fxlog xc2 for all x0. This page lists some of the most common antiderivatives. This material is provided as is without warranty or representation about the accuracy correctness or.
Integration is the basic operation in integral calculuswhile differentiation has straightforward rules by which the derivative of a complicated function can be found by differentiating its simpler component functions integration does not so tables of known integrals are often useful. 1 x ta 1e t dt 58 z eax 2 dx i p 2 p a erf ix p a 59 z e ax 2 dx p 2 p a erf x p a 60 z xe ax 2 dx 1 2a e 61 z x2e ax 2 dx 1 4 r a3 erfx p a x 2a e 2 62 2014. Sin x dx cos x c. Csc 2 dx cot x c.
Integration can be used to find areas volumes central points and many useful things. Integral of 1x2 using the integration formula the same rules apply treat n as 2. But it is often used to find the area underneath the graph of a function like this. A dx ax c.
