Question

find the points on the curve $\sqrt{x}+\sqrt{y}=\sqrt{a}$ at which tangent and normal respectively are parallel to x-axis and y-axis???

Answer 1

This is equation of a curve

y√+x−−√=A−−√

A is constant

T is a tangent of the curve from any point on it

B is y-intercept of T

C is x-intercept of T

prove that B+C= Constant
