Am I insane or is this a typo:(adsbygoogle = window.adsbygoogle || []).push({});

Consider the nonlinear DE

dy/dx = (y-x)^2 + 1

Show that the change of variables, u=x, v = y-x transforms this DE into the seperable DE: dv/du = v^2

dv = dy

du=dx

dv/du = dy/dx = (y-x)^2 + 1 = v^2 + 1

not v^2

am i wrong ???
