if i got (3/t)+ (-3t+1)/ (t2 + 1) then it would be ∫3/t dt + ∫(-3t/(t^2 + 1))dt +∫1/(t^2 + 1)dt then I am not so sure 3ln|t|+ ? + tan^-1(x/1). i don't know how to do ∫(-3t/(t^2 + 1))dt

dont we use the partial fraction that i got?

anyone?

ok so i did the partial fraction decomposition and got (3/t)+ (-3t+1)/ (t2 + 1). do i dt it or just use the integrals [1,3] and plug it in?
