Equation of tangent drawn to circle `|z| = r` at the point `A(z_0)`, is

If the tangents are drawn to the circle x^2+y^2=12 at the point where it meets the circle x^2+y^2-5x+3y-2=0, then find the point of intersection of these tangents.

A pair of tangents is drawn to a unit circle with center at the origin and these tangents intersect at A enclosing an angle of 60^0 . The area enclosed by these tangents and the arc of the circle is

If from a point P representing the complex number z_1 on the curve |z|=2 , two tangents are drawn from P to the curve |z|=1 , meeting at points Q(z_2) and R(z_3) , then :
