I am trying to enter a differential equation in mathematica. Example of such an equation is$$bigg[bigg(frac{partial{}}{partial{t}}+omega_etabigg)left(frac{partial{}}{partial{t}}+omega_nuright)+omega_M^2bigg]^2left(frac{partial}{partial{t}}+omega_kapparight)hat{u}_y=-4omega_C^2left(frac{partial{}}{partial{t}}+omega_etaright)^2left(frac{partial}{partial{t}}+omega_kapparight)hat{u}_y-omega_A^2 bigg[left(frac{partial{}}{partial{t}}+omega_nuright)left(frac{partial{}}{partial{t}}+omega_etaright)+omega_M^2bigg]left(frac{partial{}}{partial{t}}+omega_etaright)hat{u}_y,$$where the unknown $hat{u}_y$ is a function of time and...
