Answer:
Explanation:
What exactly is your difficulty can you be more specific perhaps?
If I give give you a formulae e.g. N= P¥s/ yR^2 and I don't say what each letter or symbol represents then its meaningless but if I state S = d/t and say that S = speed of an object and that equates to d (distance) divided by t (time) then hopefully you will know and be able to relate to the overall formulae
In my earlier study years I had to learn complex electrical and mechanical formulae e.g. Xl = 2pi f L ( Electrical Inductive Reactance) and its all about finding a strategy that works for you.
You have to get familiar with formulae and thats by practice, the more you use them the more you tend to remember them
