Solve the following differential equations:


Now separating variable x on one side and variable y on another side, we have,


Let 1 – x2 = t2 and 1 – y2 = t2


Differentiating we get


xdx = – tdt


ydy = – vdv


substituting these values in above differential equation



dt = – dv


integrating both sides, we get



t = – v + c


substituting the value of v and c in above equation
