if had the line integral.. int [exp(x^2/x) + x^2]dx + [y^6/y^2) + (y^2/y^3)dy] from(1,1) to (4,2) Can I cancel like terms before integrating?? how would I proceed plus what does sin(2y-y) integrate to?? is it -cos(y)??

Yes, you may cancel out terms like so: $\displaystyle \int_1^4 e^x + x^2 dx + \int_1^2 y^4 + \frac{1}{y} dy$ Also, if the function is: $\displaystyle \sin(2y-y)$ It simplifies to: $\displaystyle \sin(y)$ It's integral is: $\displaystyle -\cos(y)$ just as you said
