The tangent equation of a circle whose point passes through a point P (- 4, - 3) on the circle X & # 178; + Y & # 178; = 25 is
The tangent of a point on a circle can be obtained directly from the above formula: - 4x-3y = 25 & nbsp;, & nbsp; that is & nbsp; 4x & nbsp; + & nbsp; 3Y & nbsp; + 25 & nbsp; = & nbsp; 0
