Hello, I was wondering if anyone can help me with this problem.
Show that the line with equation 2ax+2by=a^2+b^2
is tangent to the circle with equation 4x^2+4y^2=a^2+b^2
If this is true, wouldn't the derivative of the circle equation be equal to the first equation? Would I just take the partial derivative with respect to X and then to Y?
