# Find d p / d q  if  p  = ln  ( q 2 + 1 ) .

To determine

To calculate: The value of dpdq for the function p=ln(q2+1).

Explanation

Given Information:

The provided function is p=ln(q2+1).

Formula Used:

Derivative of natural logarithmic functions is such that, if y=lnu, where u is a differentiable function of x then dydx=1ududx.

Power of x rule for a real number n is such that, if f(x)=xn then f(x)=nxn1.

Constant function rule for a constant c is such that, if f(x)=c then f(x)=0.

Calculation:

Consider the function, p=ln(q2+1)

Differentiate with respect to q
