Linear Differential Equations of Higher Order

Solution curves of a BVP that pass through two points

Linear Differential Equations of Higher Order Example 1 Consider the function We can prove that this function is a solution of the boundary-value problem Since, Therefore,

Linear Differential Equations of Higher Order

Also, When Implies Since, for any choice of ‘c’ it follows that for the problem The solution is the one parameter family

Linear Dependence and Linear Independence

Example 1 Let ‘a’ and ‘B’ are real numbers and then, and are linearly independent on any interval of the x-axis since So functions are linearly independent.
