multiplication rule for integration general form?

OpenStudy (anonymous):

ok thanks ash its just i forgot it

OpenStudy (ash2326):

Let u and v be two functions. we need to find the integral of \[\int uv \] let u be a function which is easily integrable so, the integration of uv is \[\int uv= v\int u-\int (dv \int u)\] where dv is the derivative of v. Do you understand till here?

OpenStudy (anonymous):

yap just wanted the formula thanks ash. oh and if we have x^2e then which will be u and which will v???

OpenStudy (ash2326):

e^x is easily integrable, so it'll be u v= x^2 you will have to use this formula twice:)
