Homework Statement
Using graphical means, determine how many positive roots exist, as a function of a, the the following equation.
Homework Equations
√(a2-x2) = tan(x)
The Attempt at a Solution
I've sketched graphs showing tan(x) and the semi circle overlapping for various radii. Obviously at the radius increases the number of roots increases but I have no idea how to find a relationship between them. Any help would be awesome!
