You don’t need any formulas for antiderivatives for any of the problems in FTC part 2. They only use the Fundamental Theorem of Calculus part 2 (you may want to view the video I posted on the previous post), and fundamental properties of definite integrals: see here (the blue box in the middle of the page).

In particular, you certainly do not need any techniques of integration which are to be covered later in this course! If anyone gives you advice like that, they are leading you in the wrong direction.

The point in this set of problems is to understand the relationship between definite integrals and areas, and to the functions which definite integrals define when the upper limit is a variable.

See the answers which I have posted over on Piazza as well.
