**Quick Calc Question**

Yes, you can do integration by parts. Another way is to integrate e^(xy) and then differentiate the answer w.r.t. x. Integral of e^(x y)dy = 1/x e^(xy) + c Differentiate both sides w.r.t. x: Integral of ye^(x y)dy = (y/x - 1/x^2) e^(xy) + c' If you use this method then the ...

**calculus**

Either multiply it out and differentiate is term by term, or use the function of a function "chain" rule. The first method is easier. (x + 1/x)^2 = x^2 + 2 + 1/x^2 (x + 1/x)^3 = x^3 + 2x + 1/x + x + 2/x + 1/x^3 = x^3 + 3x + 3/x + 1/x^3 Now differentiate that. For further help ...
