I want help solving differential equations

This question

my sol

syms x y(x);

eqn = diff(y,x)+sqrt(1-y^2/1-x^2)==0;

sol = dsolve(eqn);

From the uninitiated line 3

Answer 1

syms x y(x)
eqn = diff(y(x),x)+sqrt((1-y^2)/(1-x^2))==0

eqn(x) = 

cond = [y(0) == 1;y(1) == 0]  % check with some other initial conditions as well

cond = 

sol = dsolve(eqn,cond)

sol =
