Q2   Find the second order derivatives of the functions given in Exercises 1 to 10. 

          x ^{20}

   

Answers (1)

Given function is
y=x ^{20}
Now, differentiation w.r.t. x
\frac{dy}{dx}= 20x^{19}
Now, the second-order derivative is
\frac{d^2y}{dx^2}= 20.19x^{18}= 380x^{18}
Therefore,  second-order derivative is \frac{d^2y}{dx^2}= 380x^{18}
