Top Questions on Integrals of Some Particular Functions
There are many important integration formulas which are applied to integrate many other standard integrals. In this article, we will take a look at the integrals of these particular functions and see how they are used in several other standard integrals.
Integrals of Some Particular Functions:
∫1/(x2 – a2) dx = (1/2a) log|(x – a)/(x + a)| + C
∫1/(a2 – x2) dx = (1/2a) log|(a + x)/(a – x)| + C
∫1/(x2 + a2) dx = (1/a) tan-1(x/a) + C
∫1/√(x2 – a2) dx = log|x + √(x2 – a2)| + C
∫1/√(a2 – x2) dx = sin-1(x/a) + C
∫1/√(x2 + a2) dx = log|x + √(x2 + a2)| + C
These are tabulated below along with the meaning of each part.
