Find equation to the tangent at A to the circle (x-a)^2 + (y-b)^2 =r^2 where the radius through A makes an angle alpha with the x axis.

Question

Ajay · Answer

The Co-ordinates of center are (a,b) and radius is r. Since radius to A makes angle with x axis the co-ordinates of A are (a + rcos , b+rsin ). Now we know A its easy to find equation of tangent at A
