Question
Evaluate the following differential equations:
a) Variable Separable/Homogeneous Equation
(x − y ln y + y ln x)dx + x(ln y − ln x)dy = 0
b) Integrating Factor by Formula
1. (2y^2 + 2y + 4x2)dx + (2xy + x)dy = 0
2. y^2cos xdx + (4 + 5y sin x)dy = 0
c) Bernoulli’s Equation
xdy − ydx − xy^3dx − xy^3 ln xdx = 0
d) Use Substitution method
y′tan x sin 2y = sin2 x + cos2y
