A. For each differential equation, give the dependent and independent variable(s), determine whether the equation is ordinary or partial (write ODE for ordinary DE and PDE for partial DE), linear or nonlinear (write linear or nonlinear) and give also its order and degree. Copy this table in your answer sheet before you write your answers.
