Ok, ill try to explain what i did:
1.
integral of [square root of( e^t-3)dt]
Sorry i didn't know how to do the square roots symbol and the integral symbol. Anyways, I tried to set e^t-3 as u and then got dt=du/e^t. Then I plugged in dt and couldn't go on after that.
2. integral of x^2[e^(x^3)]dx
so uh... u substitution? but then what?
Ok basically, i think i don't know what your supposed do when u need to do a u-sub with e^something. Your help would be most appreciated.
