What is an example of an initial value problem?
For example, if we have the differential equation y′=2x y ′ = 2 x , then y(3)=7 y ( 3 ) = 7 is an initial value, and when taken together, these equations form an initial-value problem.
The differential equation y''−3y′+2y=4ex y '' − 3 y ′ + 2 y = 4 e x is second order, so we need two initial values.What is an example of an ODE equation?
Give an example.
An ordinary differential equation is an equation which is defined for one or more functions of one independent variable and its derivatives.
It is abbreviated as ODE. y'=x+1 is an example of ODE.Partial differential equations
For example, ∂ 2 u ∂ x ∂ y = 2 x − y is a partial differential equation of order 2.
A solution of a partial differential equation is any function that satisfies the equation identically.
