Calculus Level 4

If $$\color{purple}{\phi}$$ and $$\color{brown}{\xi}$$ are the order and degree of the differential equation whose general solution is

$\large y = \color{red}{a}\sin^2(x) + \color{magenta}{b}\cos^2(x) + \color{blue}{c}\sin(2x) + \color{green}{d}\cos(2x)$

Calculate $$\color{purple}{\phi} + \color{brown}{\xi}$$.

Detals :

• $$\color{red}a , \color{magenta}{b} , \color{blue}{c} , \color{green}{d}$$ are arbitary constants.
• Choose None of these, if you think degree is not defined.
