Which calculator is best for postgraduate electrical engineering studies?

AI Thread Summary
For a master's study in electrical engineering, particularly in communication and computer networks, the TI-89 is recommended for its advanced capabilities, including graphing, matrix operations, and solving integrals. Although it is priced around $140, its features justify the cost. The TI-36X is a budget-friendly alternative at approximately $10, suitable for basic engineering calculations but lacking advanced functions. The TI-Nspire™ CX CAS is less favored compared to the TI-89 for this level of study. Additionally, the TI-89 can be enhanced with EE-Pro software, which is beneficial for electrical engineering tasks. For those seeking lower-cost options, using a classical scientific calculator or software applications on devices like Android or iPad can suffice, provided the user is proficient with them. The HP 50G is another option, but users should familiarize themselves with RPN calculator apps before making a purchase.

HI
I need your advice to buy a calculator to be used in master study in electrical engineering-communication and computer networks and also useful as an engineer (electrical engineer/Electronics & Communication)
Thanks in advice
 
Computer science news on Phys.org
TI-89

that being said I rarely use a calculator anymore. I use matlab/excel for 99% of my computation
 
Yep, TI-89 is the ticket. A little pricey at $140 or whatever, but worth it.

You can buy a "secondary" calculator, the TI-36X for $10 that works pretty well for engineering as long as you don't need graphs, matrices, multivariables or integrals solved. TI-36X is also legal on the FE and PE Exams.
 
Thanks
what about TI-Nspire™ CX CAS is it or TI-89 Titanium
 
The Ti-89 is better for your needs than the Ti-nspire CX CAS. At your level, you could go cheap ie Ti-36X pro and an Android or I-pad app or cheap software alternative as well.

The Ti-89 also comes with EE-Pro or it is free to download for a Ti-89. That software used to cost Hp calculator owners around $100 before Ti bought the software out and took it away from the Hp market.
You might consider an Hp 50G, but you should play with an RPN calculator app before you spend real money on one.

Any classical scientific calculator should be more than enough... if you know how to use it.

Thread 'Urgent: Physically repair - or bypass - power button on Asus laptop'

Asus Vivobook S14 flip. The power button is wrecked. Unable to turn it on AT ALL. We can get into how and why it got wrecked later, but suffice to say a kitchen knife was involved: These buttons do want to NOT come off, not like other lappies, where they can snap in and out. And they sure don't go back on. So, in the absence of a longer-term solution that might involve a replacement, is there any way I can activate the power button, like with a paperclip or wire or something? It looks...
