Study Notes
Ordinary Differential Equations
- Ordinary differential equations (ODEs) of first order and first degree can be classified into different forms.
Forms of ODEs
- Homogeneous differential equations: a type of ODE with a specific structure.
- Exact differential equations: another type of ODE that can be solved exactly.
- Reducible forms: ODEs that can be transformed into a solvable form using substitutions or other methods.
Methods of Solution
- Method of substitution: a technique used to solve ODEs by substituting a new function or expression into the original equation.
