Mathematics is an eternal part of Physics. So if you want to have a smooth journey dealing with physics, then the Basic Mathematics will be a good choice to go for. Now if you are well done with calculus & trigonometry then no need to do the Basic Mathematics for HCV.

If you are starting your Physics i.e., you are in 11th then go through the chapter and solve the problems as this will help you up to get acquainted with the techniques and though process required to solve the problems in Physics.

I hope this helps. Wish you a great day!
