# Thread: How to input Dirac Delta Function in Maple

1. ## How to input Dirac Delta Function in Maple

I want to solve the initial value problem
$x''-4x=2\delta(t-4)$
$x(0)=x'(0)=0$

I know the first part involves

diff(x(t), t, t)-4*x = 2

and that I will need to use dsolve but I'm not sure how to input the dirac delta function.

2. The function is

Dirac(t-4) Note that you must have the capital d
