If I can offer some advice as a former Calc I student, since you are focused on ML, ignore integrals and the fundamental theorem of calculus. Instead, understand the connection between derivatives and antiderivatives and become practiced with the rules of derivation: product rule, quotient rule, trigonomety functions (tanh is part of hyperbolic trigonometry), exponentiation, logarithms, and the chain rule. Using derivatives to find local minima and maxima will also be useful. You should be able to look at the graph of a function and quickly visualize the graph of its derivative.
