So my professor was going over integration by part and using the tabular method. He use the problem:
(the integral sign, big swoosh like thing) (3t+9)^3(2t+e^2t)dt
Now, to find the derivative, I believe he used the chain rule, perhaps? Only thing is, I am not certain how I would use the chain rule on this one? Somehow, I do recall him showing on the outside he obtained
3x3(something) for the first derivative
3x2x9(something) for the second derivative
But I do not know how.
Any help would be appreciated!
