Hey guys,
I have to find the equations of the lines which pass through the origin and are tangent to the circle (x-2)^2 + (y-1)^2 = 4, and just by drawing it I can tell one of the tangents is x=0. But I can't find the other one. The book says the answer is y=-3/4x and I don't know how to start. Thanks
