In a calculus you start with a formula for a function, and then computes the rate of change of that function. But in the real world, you usually don't have a formula. The formula, in fact, is what you would like to have: the formula is the unknown. What you do have is some information, given by the laws of science, about the way in which the function changes.

Go pick up a book called "...The Principia" by Sir Isaac Newton. He created the Differential Calculus to help him calculate and describe the effects of his theories of motion and gravity. If he invented it, he should be able to explain it best. And, it is actually an interesting read.

There is no such formulae. read a calculus book

If you can find the first and second derivatives of an equation, you are set.

f'(x)=(hâ0)lim (f(x+h)-f(x))/h
(f(x)+g(x))'=f'(x) + g'(x)
(n*f(x))' = n*f'(x)
(f(x)g(x))' = f'(x)g(x) + g'(x)f(x)
(f(x)/g(x))' = (f'(x)g(x) - g'(x)f(x))/g(x)^2
f(g(x))' = f'(g(x))*g'(x)
(x^n)' = nx^(n-1)
(ln x)' = 1/x
Those are the big ones.
