Welcome back I'm just trying to show you as many examples of possible of solving differential equations exact differential equations one trying to figure out whether the equations are exact and then if you know they're exact how do you figure out the Zhai and figure out the solution of the differential equation so the next one in my book is 3x squared minus 2xy plus 2 times DX plus 6y. Since C is an arbitrary constant, D = eC is an arbitrary positive constant (Recall that eC is always positive, no matter what the sign of C) Finally, recalling that p = q implies that p = ±q,weobtain y = ±Dekt(7) Since D is an arbitrary positive constant, we can set E = ±D and rewrite.

One way to solve this is based on recognizing that the left side is sinh(x) which makes your equation sinh(x) = 2 (If you have never heard of sinh (hyperbolic sine), then skip down to "Without sinh" below).
