2nd order derivative of x square+6xy+y square
Hello,
The given equation,
x^2+6xy+y^2
Differentiating the above equation
d/dx(x^2+6xy+y^2)=2x+6y
differentiating the above solution to get the second order derivative we get,
d/dx(2x+6y)=2
therefore, the second order derivative of the above equation that is, x^2+6xy+y^2 is 2.
Hope this helps.
All the best!
