 |
|
I'm trying to make a good unit step function that doesn't bog down my TI-89.
If you dont' know what it is, all it means is that the parameter = 0, then it returns a 1, else it returns a zero. For example:
u(0) = 1
u(5) = 0
u(12) = 0
5 ~> t
u(t - 5) = 1
See? I tried making a program with simple IF statements, and it works fine until I try to use them in an integral, or try to graph it. Then the calc gets really bogged down. Is there a more efficient and quick way to perform this function?? |
