Helpful video for using my hp prime and ti nspire. With HP Prime I just did ilaplace on(3/s^2 x (s+2),s,t) and it gave correct answer after using simplify. I had no need use partial fractions. Answer was 6t+3e^(-2t) -3 all divided by 4 ie a more simplified answer of one in video. Or if then use expand() function it is shown in same form as the video as separate fractional terms.
A bit late to answer the problem with HP prime but, with HP Prime you can use laplace(3*t,t,s) in CAS then it will give answer 3/S^2. Similarly, laplace(3*t,t*p) = 3/p^2. for inverse laplace ilaplace(3/s^2,s,t) Prime will give answer 3*t.. Hope it will be useful for some one with HP Prime.
HP Prime: write laplace(t/3, t, s) and you will get the answer in terms of s. If you don't specify any variable, the default is x. In general when using any function like laplace(), put the cursor inside the parenthesis and press help button on the up right and you will see some examples on that function. fx-CG500/Classpad II: To avoid writing the expression in the interactive popup window, you may drag the stylus on a pre-entered function in the workspace and press interactive after that. This could be helpful in 2 ways, first you will be entering the function in textbook format rather than linear format, and the second you can go back to one of the previous calculations which could be long complicated expression in the workspace and simply drag the stylus on that expression to perform interactive calculation on it. Thanks
Thanks for the tips. I had frankly forgotten about using the comma separated variables (although I used it with the HP50G). Do you know if the HP Prime has a wizard like the Interactive feature of the Class pad that will prompt for the variable and the parameter? I really appreciate comments like this since I learn and so do others.
@@tomtektest8042 ? Can formulae be written into any of the calculators simply by using a stylus? Thanks for your excellent presentation, great revision of the principles.
As in CASIO for Laplace : [ Expression : 3t , Inde var: t , Parameter: s ] ....... the same way in HP Prime : laplace(3t , t , s) .... it gives the same result: [ 3/s^2]
This video was really helpful, since I recently bought a casio classpass for computer engineering.

Thanks for the demonstration. I recently bought the Casio FX cg500. I used to use tables to lookup LaPlace transforms but not anymore.
Great video you made Sir, it was really helpful

Thank you for the demo of these three calculators, more of that please Sir.
Thanks alot for this wonderful video
What wonderful videos you produce. Keep them coming!

HP prime does show 't' and 's' for laplace. just take a look at the manual...
gracias, me fue de gran ayuda

How would you put in the initial conditions in the casio cg500?
Casio is the best calculator
There's no problem with the laplace function. laplace(f(t),t,s). This is basic CAS syntax EE professors are very much aware of.
HP Prime ... laplace(Expr,[Var],[LapVar])
Yay. Thanks for the comparison.
