To find center of a circle in standard form and general form like the one used in video, just take derivative w.r.t x or y term of circle. For example: x²+y²-8x-10y-128=0 For center C(h,k), i need h so i will take derivative w.r.t x. So, 2x+0-8-0-0=0. (EVERYTHING except x will be treated as constant term) (remember it is for this scenario only that we treat y as constant and not y' ) 2x=8. => x=4 For k, take derivative w.r.t y, 0+2y-0-10-0=0 2y=10. => y=5 Hope it helps.

More easy method Just multiply the coefficient of x and y by -1/2 , to get coordinates of cente You don't need to differentiate at all!

Call me overly cautious, but I would first check that the desired point of tangency is actually on the circle (I checked. It is).

Why are you using the coordinates of the point and that of the centre to find the slope of the radius??

Sir, shall I use to get tangent equation directly from given circle equation by this way: x*{-8} + y*10 - 4{x-8} -5{y+10} -128=0 which implies 12x - 5y +146 = 0

So does it mean that the equation of the normal line to the circle is the same as the equation of the radius

Hello, I'm having a question which is more of the same like that but a bit different,. Find an equation of each tangent line drawn to from the point (5,1) to the circle x^2 + y^2 = 14. Please I need my feedback.

We found the centre by completing the squares first. Then the equation of tangent as it is perpendicular to the radius. Hope that helps. Thanks
