Rules of Differentiation

p {margin: 0; padding: 0;} Date Rules of Differentiation A function is differentiable at a point if despite any side approach to the point in its domain (from left or right) the derivative is the same and a finite number. yolx y=x" y= x 0 If f(x) and (g(x) are two differentiable function in their common domain. then : 1) [f(x) 19' '(x) (summation be sub rules They can extend to n functions) 2) [F(x).9(x)]' = f'(x) 9(x)+g'(x).f(x) (Multiplication can be extended pule ant r to function). 3) (f(x)] = (Quotient rule) 9(x) [g(x)] 4) [f(G(x)]]' g'(x).f' (a(x)) (chain Rule)
