# dy/dx = - sqrt(1-y^2)/sqrt(1-x^2) #
Explanation:
We have:
# sin^(-1)x + sin^(-1)y = pi/2 #
Using the standard result:
# d/dx sin^(-1) x = 1/sqrt(1-x^2) #
we can implicitly differentiate the first equation, giving:
# 1/sqrt(1-x^2) + 1/sqrt(1-y^2) dy/dx = 0 #
# :. 1/sqrt(1-y^2) dy/dx = - 1/sqrt(1-x^2) #
# :. dy/dx = - sqrt(1-y^2)/sqrt(1-x^2) #
