280 Initial Conditions

A value of a function at a fixed point of its domain that is used to determine a unique solution of an equation.

definition [d] (Initial Condition) From Stewart: in many physical problems we need to find the particular solution that satisfies a condition of the form

  • \(y(t_{0}) = y_{0}\) .

This is called an initial condition, and the problem of finding a solution of the differential equation that satisfies the initial condition is called an initial-value problem.

where

  • \(y\) is the unknown function.
  • \(t_{0}\) is a fixed value of the independent variable.
  • \(y_{0}\) is the prescribed value of \(y\) at \(t_{0}\).
