need help with part b, pls explain too
2t is the derivative of t^2, so this function follows the formula f’(x) [f(x)]^n which integrates to becomes [f(x)]^(n + 1) divided by (n + 1).
It’s basically akin to integrating x^n, except that this time it’s f(x) instead of x (so we need the “accompanying” f’(x)).
