What is the double derivative(y") of x^2+y^2=25

Thank you!

dy/dx of x^2 + y^2 = 25 is gonna be 2x + 2y(dy/dx)=0

Simply take the second derivitive of that to find your answer.

This is assuming that y is your dependent variable mind you, if y is the independent then you will be finding dx/dy and it will be 2x(dy/dx) + 2y=0

Thank you!
