- Problem Statement
- I tired integration by parts but it leads me nowhere. How do you solve this using methods of integration that you learn early on. (U-sub - importer integrals)?

- Relevant Equations
- is this integral possible to solve without using feynamns technique?

U= 1/x dV= sin(x)

dU = -1/x^2dx V= -cos(x). lim b--> infiniti (integral from [0,b]) = 1/x(-cos(x)) - integral(1/x^2(cos(x)) dx

dU = -1/x^2dx V= -cos(x). lim b--> infiniti (integral from [0,b]) = 1/x(-cos(x)) - integral(1/x^2(cos(x)) dx
