# This'll be a doozy

Let $$a$$ and $$b$$ be given real numbers. Solve the system of equations

$\frac {x - y \sqrt {x^2 - y^2}}{\sqrt {1 - x^2 + y^2}} = a,$

$\frac {y - x \sqrt {x^2 - y^2}}{\sqrt {1 - x^2 + y^2}} = b$

for real numbers $$x$$ and $$y$$.

Nice problem!

Solutions:

$$x= \dfrac{a+b\sqrt{m}}{\sqrt{1-m}}$$ and $$y= \dfrac{b+a\sqrt{m}}{\sqrt{1-m}}$$,where $$m = a^2 -b^2$$ · 8 months, 1 week ago
