Question
Show that the inhomogeneous equation y" + y = sec x, has the homogeneous solutions y₁ = cos x and y2 = sin x. (Plug them into the homogeneous equation and show they check.) Find the Wronskian for this pair of solutions, determine functions u(x) and v(x) to apply the variation of parameters method, and the general solution.
No conditions are given.
Normally what constants you use are arbitrary, but for grading purposes use A as the coefficient for cosine and B as the coefficient for sine in your general solution.
The Wronskian W(cos x, sin x) =
u(x)= log(sec (x))
v(x)=
X
The general solution is
y (x)= -cos (x(log(sec (x)))) +xsin(x) + A-cos(x) +B-sin(x)
