ey-2x(1+x2)dx + cosydy = 0
(ey / e2x)(1+x2)dx = -cosydy
(e-2x + x2e-2x)dx = -e-ycosydy
(-1/2)e-2x + ∫x2e-2xdx = -∫eycosydy
Integrate by parts twice.

asked 11/03/23e^(y-2x) (1 + x²) dx + cos y dy = 0 when x = 0 and y = 0
a. 2e^2x (cos y - sin y) + e^y (2x^2 + 2x + 3) = 5e^(2x+y)
b. 2e^y (cos y - sin y) + e^2x (2x^2 + 2x + 3) = 5e^(y-2x)
c. e^2x (sin y - cos y) + 2e^y (2x^2 - 2x - 3) = 5e^(2x+y)
d. e^2x (cos y - sin y) + 2e^y (2x^2 + 2x + 3) = 5e^(y-2x)
ey-2x(1+x2)dx + cosydy = 0
(ey / e2x)(1+x2)dx = -cosydy
(e-2x + x2e-2x)dx = -e-ycosydy
