1) INT (arctane^x/2)/[e^x/2(1+e^x)]dx ??????
2)INT dx/[x(1+x^3+x^6)^1/2]????????
3)INT (e^2x)/(x^2-3x+2)dx ???????
4)INT (ch^2)(sh^2)dx????????
5)INT (ch^4)dx ????????
please help meeee
Make sure you write these accurately:
INT (arctane^x/2)/[e^x/2(1+e^x)]dx
Do you mean:
INT arctan(x/2)/[e^(x/2)*(1 + e^x)] dx ?
Go through all the problems that you need help on and make sure they are written accurately, otherwise I can't help you if I'm solving the wrong problem.
