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?

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

5. ash2326 Group Title

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