Rules of Differentiation
A function is differentiable at a point if despite any side approach to the point in its danain (from left or right) the derivative is the same and A finite number.
le f(x) and 6 (x) are two differentiable function in ther Common domain, then:
1) [f(x)+g(x)] = f'(x) ± g'(x) (summation t-sub rules They coin the extend to in furickond
2) [f(x).g(x)] = f(x).g(x)+g(x). f(x) (Mullention rule and can be extended t
3) 「f(x) = f(x) -9ム)ーグ(x) (f(x)
[(x)]2
(Quotiens rule)
4) [f(g(x))] = g(x)f(の(x))
