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.
