Homework Statement
(2y^2 - 4x + 5) dx = (4-2y+4xy)dy
i divided by dx and rearranged...
(-2y^2 + 4x - 5) + (4-2y+4xy)dy/dx
this is M....and this is N
then took partial derivatives...
M_y = -4y
N_x = 4y
M_y not equal to N_x, therefore not exact..
but it is so close that i suspect i am making some mistake..
??
