The HP.org site has an emulator (technically a simulator) for download for Windows desktops. If you need a windows store copy you can try the copy here.
Other graphing calculators still slug along at slow speeds for plotting. The HP prime on the other hand plots with lightning speed.
If you want to buy on one Amazon you can go to my affiliate link. This is my go to calculator for desktop, smartphone, AND physical calculator. The buttons are nice and clicky. I bought mine several years ago to replace a TI-85 that died after 20 years.

The Applied Technology Council (ATC) has made a web tool for determining structural hazards by location. This is a useful tool to document code specified design values for snow, wind, seismic loading criteria. You can find their tool at https://hazards.atcouncil.org/#/ .

About the ATC:
The Applied Technology Council (ATC) is a nonprofit, tax-exempt corporation established in 1973 through the efforts of the Structural Engineers Association of California. ATC’s mission is to develop and promote state-of-the-art, user-friendly engineering resources and applications for use in mitigating the effects of natural and other hazards on the built environment. ATC also identifies and encourages needed research and develops consensus opinions on structural engineering issues in a nonproprietary format. ATC thereby fulfills a unique role in funded information transfer.
ATC is guided by a Board of Directors consisting of representatives appointed by the American Society of Civil Engineers, the National Council of Structural Engineers Associations, the Structural Engineers Association of California, the Structural Engineers Association of New York, the Western Council of Structural Engineers Associations, and four at-large representatives concerned with the practice of structural engineering. Each director serves a three-year term.
Project management and administration are carried out by a full-time Executive Director and support staff. Project work is conducted by a wide range of highly qualified consulting professionals, thus incorporating the experience of many individuals from academia, research, and professional practice who would not be available from any single organization. Funding for ATC projects is obtained from government agencies and from the private sector in the form of tax-deductible contributions.
The corporate headquarters for ATC is located in Redwood City, California, with a satellite office in Arlington, Virginia.

Wabbitemu creates a Texas Instruments graphing calculator right on your Android device. Wabbitemu supports the TI-73, TI-81, TI-82, TI-83, TI-83 Plus, TI-83 Plus Silver Edition, TI-84 Plus, TI-84 Plus Silver Edition, TI-85, and TI-86. Fast and convenient, Wabbitemu allows you to always have your trusty calculator with you. Because Wabbitemu is an emulator, the calculator it creates will act exactly like the real thing.
Wabbitemu, like all emulators, requires a ROM image. Wabbitemu includes an easy to use setup wizard that will help you create a ROM image for your TI.
If you need to make a ROM, you can download it from your calculator. If you need help try clicking on appropriate link below:
The Wolfram|Alpha blog has published some information on plotting functions with Wolfram|Alpha. The plots come out quite nice whether 2D, 3D, or contour, and you don’t need to install any software to do some quick plots.
Plotting Functions and Graphs in Wolfram|AlphaMay 17, 2011Plotting functions in the Cartesian plane is such a simple task with Wolfram|Alpha: just enter the function you are looking to graph, and within seconds you will have a beautiful result. If you are feeling daring, enter a multivariate function, and the result will be a 3D Cartesian graph. Wolfram|Alpha is certainly not limited to Cartesian plotting; we have the functionality to make number lines, 2D and 3D polar plots, 2D and 3D parametric plots, 2D and 3D contour plots, implicit plots, log plots, log-linear plots, matrix plots, surface of revolution plots, region plots, list plots, pie charts, histograms, and more. Furthermore, in Wolfram|Alpha we can generate specialized plots for illustrating asymptotes, cusps, maxima, minima, inflection points, saddle points, solutions of ordinary differential equations, poles, eigenvalues, series expansions, definite integrals, 2D inequalities, interpolating polynomials, least-squares best fits, and more. Let’s take a look at the plotting functionality in Wolfram|Alpha, some of which is newly improved!We will start simple with 2D Cartesian plots.
Here’s a great TI emulator for your Android device. You will have to download your own ROM, but it works great.
Andie GraphGet a TI-82, TI-83, TI-85, AND TI-86 emulator for your phone!ROM NOT INCLUDED. Due to a request from TI, this app will NOT WORK until you EXTRACT YOUR OWN ROM. See http://supware.net/roms for details. This is similar to other emulators on the market: GameBoid, SNESoid, GBAEmulator, NESoid, psx4droid, etc The TI-8X series of calculators work great as standalone calculators, showing 8 lines of history, using standard mathematical notation.
Microsoft Mathematics 4.0 is a free mathematics program from Microsoft (if you couldn’t already tell that from the name) for Windows. It is definitely a better upgrade to the standard windows calculator, and keeps a notebook of calculations/graphs. It is more geared toward students, but can be useful for a general graphing calculator for anyone. It can also be used with a tablet computer and stylus to accept written input.
Microsoft Mathematics provides a graphing calculator that plots in 2D and 3D, step-by-step equation solving, and useful tools to help students with math and science studies.
Microsoft Mathematics provides a set of mathematical tools that help students get school work done quickly and easily. With Microsoft Mathematics, students can learn to solve equations step-by-step while gaining a better understanding of fundamental concepts in pre-algebra, algebra, trigonometry, physics, chemistry, and calculus.
Microsoft Mathematics includes a full-featured graphing calculator that’s designed to work just like a handheld calculator. Additional math tools help you evaluate triangles, convert from one system of units to another, and solve systems of equations.
For those of you who just loved your RPN HP48 graphing calculator and have an android phone, this app is for you. Just looking at the screen brings back memories. The developers have faithfully recreated the original calculator’s look and feel. If you are a RPN fan, and you need a little more power than just a scientific calculator on your phone, then this is definitely worth a look. From the developers:
HP 48 lives again on Android!
Emulator of the HP 48 scientific calculator, using RPN. Port of the X48 project (sources available on github). HP48’s “grayscale mode” cannot be emulated.
RealCalc Scientific Calculator for Android is made by Quartic Software. This is a great standard scientific calculator which only shows one entry at a time. There is also a setting for RPN functionality. This is a great substitute if you want to leave your scientific calculator behind and need to do some light calculations using your Android phone. This app is not very processor intensive. Two screenshots from the developer’s website are below:
This week, The Engineering Zone will feature calculator applications.
One of my Favorite PC calculators is GraphCalc (also available for Linux). It is fast, easy, and you can use your number pad for input. Even though it was last updated in 2003, it still works great on newer computers with Win7.
GraphCalc is ready to use out of the box. Don’t bother reading the documentation. Just start the program and you’ll see how easy it is to use.
This software is free and open source, so you can use it everywhere. You can even export the 3d plots to DXF files. These files can be imported into other programs. This is convenient for surfaces that can be defined by a mathematical equation.
