Classification of ODEs Determine the order and linearity/nonlinearity of the following scalar ODEs (a) (10 points) y"(t) sin(t) y(t) +t2 (b) (10 points) y'(t)-sin(y(t))- t Note: If the equation is linear, vou need to prove it by the linearity property. If the equation is nonlinear, only determine the term in the equation that makes it nonlinear S. S.
(1 point) It can be helpful to classify a differential equation, so that we can predict the techniques that might help us to find a function which solves the equation. Two classifications are the order of the equation -- (what is the highest number of derivatives involved) and whether or not the equation is linear Linearity is important because the structure of the the family of solutions to a linear equation is fairly simple. Linear equations can usually be solved...
