chapter 34: simultaneous linear differential equations. chapter 35: method of perturbation. chapter 36: non-linear differential equations Differential equations: exponential model word problems AP.CALC: FUN‑7 (EU) , FUN‑7.F (LO) , FUN‑7.F.1 (EK) , FUN‑7.F.2 (EK) , FUN‑7.G (LO) , FUN‑7.G.1 (EK) Google Classroom Facebook Twitter Ordinary differential equation is the differential equation involving ordinary derivatives of one or more dependent variables with res pect to a single independent variable. Typically, the resulting differential equations are either separable or first-order linear DEs. The solution to these DEs are already well-established. Alternative way to solve them is by using the method of Laplace Transforms. Non-analytic ways to solve the mixing problem includes: finite interval method, and calculator techniques.
