Gamma Function Intuition Derivation And Examples By Aerin Kim Towards Data Science

This is a very common IBlevel question, which is solved with using the technique of a "disguised quadratic" The first thing we want to do in finding the inverse is swapping the places of x and y in the equation y=f(x), to obtain x=f(y), because finding the inverse is equivalent to reflecting the curve in the line y=x, ie interchanging the x and y coordinatesTo ask Unlimited Maths doubts download Doubtnut from https//googl/9WZjCW If `f (x/y)= f(x)/f(y)` ,`AA y, f (y)!=0` and `f' (1) = 2`, find f(x)Df = f 0(x 0) dx x x 0 L(x) y f(x) x df dx = x f f(x ) 0 Differential of functions of more than one variable Definition The differential at (x 0,y 0) ∈ D of a differentiable function f D ⊂ R2 → R is the linear function df (x,y) = L(x,y) − f (x 0,y 0) Remark The linear approximation of f (x,y) at (x 0,y 0) is the plane L(x,y
