    A differential equation of order three is an equation with an unknown function that involves the third derivative of that function.


    [tex]\frac{d^3y}{dx^3}= 0[/itex]
    where y is an unknown function of x.

    [tex]y^2\frac{d^3y}{dt^3}- 7y\frac{d^2y}{dt^2}+ sin(y)\frac{dy}{dt}+ e^{ty}= ln(t)[/tex]
    where y is an unknown function of t.
