${\int}_{0}^{2\pi}\frac{1}{{\mathrm{sin}}^{4}x+{\mathrm{cos}}^{4}x}$

1) I've tried multiplying by ${\mathrm{sec}}^{4}x$ and doing u substitution, but It used crazy amounts of upper level maths

2) I've tried double/half angle identities to simplify down to $\frac{1}{1-\frac{1}{2}{\mathrm{sin}}^{2}2x}$

3) I've mixed strategies and came up with $\frac{4\mathrm{cos}2x}{4\mathrm{cos}2x-\mathrm{cos}3x\mathrm{cos}x}$

Reduce the system

(D2 + 1)[x] − 2D[y] = 2t

(2D − 1)[x] + (D − 2)[y] = 7.

to an equivalent triangular system of the form

P1(D)[y] = f1(t)

P2(D)[x] + P3(D)[y] = f2(t)

and solve.
