#How to apply Standard Integral formulas ?

Question

jhannybean · Answer

By relating them to their identities? example: $\large \int \sin(x)dx = -\cos(x)+x$

jhannybean · Answer

Here's a web page filled with various integrals http://integral-table.com/integral-table.html#SECTION00003000000000000000

@Jhannybean  do you know what standard  Integral formulas are ?

jhannybean · Answer

I believe they would pertain to sine, cosine, tangent, secant, cosecant, and cotangent, perhaps?

jhannybean · Answer

You can always do a google search of the integrals you need to understand...

I know @Jhanny but i wana know how to apply them,like this formula,mentioned below  

$$\int\limits_{}^{}dx/x ^{2}-a ^{2}=1/2a    \log \left| x-a/x+a \right| + C$$

how to apply this one to a specific type of question ?

jhannybean · Answer

Ohok,you hadnt mentioned any specific problem. Lets see.

thats what idk how to go through,would you please tell me the same ?

jhannybean · Answer

Depends on what your problem consists of, there are certain u substitutions and other methods of simplifications that will simplify your problem into this type of following identity, $\large \int {\cfrac{dx}{x^2 -a^2}} = \frac{1}{2a} \ln \left|\cfrac{x-a}{x+a}\right| + c $
