if X%5E2%2Fa%5E2 - Y%5E2%2Fb%5E2 = 1 then Y is
multiply equation by a^2b^2, cancel the denominators
x%5E2b%5E2 - y%5E2a%5E2 = a%5E2b%5E2
x%5E2b%5E2 - a%5E2b%5E2 = y%5E2a%5E2
divide by a^2
y%5E2 = %28%28x%5E2b%5E2%29-%28a%5E2b%5E2%29%29%2Fa%5E2
y%5E2 = %28b%5E2%28x%5E2-a%5E2%29%29%2Fa%5E2
Find the square root of both sides
y = sqrt%28b%5E2%28x%5E2-a%5E2%29%2Fa%5E2%29
