I've tried literally everything I have in my knowledge to try to get this problem. I am to find the tangent linewith a positive slope to these two circles (the one on the left is x^2+y^2=1, the one on the right is y^2+(x-3)^2=4), and find the two points which the line hits these circles. Seriously, any help at all, would be the most fantastic thing I'd ever read. Thanks.
