Tangents are drawn to the circles $x^{2}+y^{2}=a^{2}$ and $x^{2}+y^{2}=b^{2}$ at right angles to one another. The locus of their point of intersection is (a) $x+y=a$ (b) $x^{2}+y^{2}=a^{2}+b^{2}$ (c) $a x+b y=1$ (d) $x^{2}+y^{2}+a b=0$
Tangents Find equations for the tangents to the circle $(x-2)^{2}+(y-1)^{2}=5$ at the points where the circle crosses the coordinate axes.
