Start w/ solution some function 7(x,y) =c constant constant. 8 z = f1xciy) dz = o"c,g) = ltdx+ftdy=o. Mice, 33dxc (ec" - 1) dy = 0. Ime in f in ey lazy) solution is some function f(x,y) = c. & y derive w/ respect to y treat 4 as a constant. 2xc v so based on these 2 equations that the solution must satisfy, 2 x this is a constant w/ respect to c only! include y it can still: becauseifderived the fig) = rye"+cy) Trgesisiy)) = 32 - x< + ("ly) = cc "-1 (y) = c2-1-142.
