Hii, thank you :) I did: dy + (exSec(y)-Tan(x))dx = 0 0 ≠ exSec(y)Tan(y) (∂N/∂x ≠ ∂M/∂y) So, we need an integrating factor. If we use e-ax; -ae-ax = e(1-ax)Sec(y)Tan(y) appears. Shouldn't be "a" is a real value? Also; I tried to modify equation with ArcSecant function to become...

I tried to solve it but confused. Pls. help me to solve this equation: dy/dx + (e^x)*Sec(y) = Tan(x); (hint: integrating factor is e^-ax, and a is unknown, a ε ℝ, find it, solve the equation) Thnx.
