@@bonjournito First of all: If i want the solutions of sin(x)=1on a HP Prime, I only get the solution x=Pi/2. If I do the same on a TI-Nspire CX II-T I get all solutions x=2Pi*k+Pi/2 with Integer k. But more serious was the fact that the solve function works unreliably: The solutions of a quadratic equation were sporadically omitted. When I deleted the memory the solutions were there again. The HP Prime certainly has a lot of features and feels high quality and is fast. But if a central function doesn't work reliably, that's not acceptable to me.
why didn't you include the best calculator? The HP Prime G2?
The TI 83 Plus calculator does not have a colour screen! Ever heard of the HP Prime calculator? Hmm?
Not even a mention about HP calculators and, above all, the HP Prime. Very, very good....
Unfortunately HP Prime has problems with solve, so I am very disappointed about HP.
@@berndkrucan you explain more please?!

@@berndkru I see! I use an app called CAS Calculator. It’s free and gives me the same as your TI.
How can it be that the HP prime and Casio Classpad are not even mentioned? Bad review.
