The solution of the DE ` (dy )/(dx) + sqrt ((1 -y ^(2))/( 1- x ^(2))) = 0 ` isA. `y + sin ^(-1) y = sin ^(-1) x + C `B. `sin ^(-1) y - sin ^(-1) x = C `C. ` sin ^(-1) y + sin ^(-1) x =C `D. none of these

Answer» Correct Answer - C
` int (1)/(sqrt(1 - y ^(2))) dy + int (1)/(sqrt (1 - x ^(2))) dx = C rArr sin ^(-1) y + sin ^(-1) x = C `.
