Problems when i want to do Laplace Transforms

[Ayanaju]

Hi guys,

I've bought my Ti-89 Titanium last month and i'm still trying to learn it.

So i was studying and tried the Laplace transform on it, but, for my surprise, this fabulous calculator did not gave me an answer, it just repeats what i've wanted to know under it.

So, can you say which configuration is necessary for it to do Laplace Transforms?

Sorry about my english, that's not my mother-language.

tks

I imagine you used "s" as the laplase operator. Unlike you, the TI-89 sees this as a simple variable (just like "x" or "y"), not a laplase operator that needs to be transformed to time-domain.

I hate to sound redundant, but do yourself a favor and do the calculations manually. You will never have to use it outside of class, but it is important stuff nonetheless to commit to memory.

Cheers!
