Differentiate by the first principle.
Let us consider
By quotient rule derivative of
[The quotient rule of differentiation is defined as the ratio of two functions (1st function / 2nd function ), is equal to the ratio of (differentiation of 1st function the 2nd function differentiation of the second function the first function ) to the square of the 2nd function]
by simplifying the equation
Thus, differentiation of by the first principle is.
