Separating variables: 1−y2dy=−1−x2dx. Integrating: sin−1y=−sin−1x+C, i.e., sin−1x+sin−1y=C (D). Using cos−1y=π/2−sin−1y, we also get sin−1x−cos−1y=C (B) and cos−1x+cos−1y=C (E). Hence B, D, and E only.
General solution of the differential equation dxdy+1−x21−y2=0 is
A. tan−1x+tan−1y=C
B. sin−1x−cos−1y=C
C. x1−y2−y1−x2=C
D. sin−1x+sin−1y=C
E. cos−1x+cos−1y=C
(where C is arbitrary constant)
