It usually means symbolic machines that can directly handle integrals and differentiation are not permitted. This might mean using standard scientific, graphics and even programmable calculators are ok but it might not for a given exam. So much silliness that we didn't used to have to deal with.Īs a UK exam invigilator (and HP calc enthusiast), I know our awarding body - JCQ - are doing their best to ensure that no candidate has an unfair technological or functional advantage over those who are adhering to the published rules.
Especially since dedicated calculator hardware is basically "dead man walking" in this world of large cell phones and tablets, except in the education market, where the curriculum requires silliness like machines that blink LED codes to assure the teacher that they are running in crippled mode. So the $20 - $25 app had to be severely crippled. But of course, HP wants you to buy their hardware. And I might even use it as the standard calc app on my Galaxy Note 4 if you could save your work, and if the app didn't waste so much space on borders that the usable area of the app is tiny. If you're into calculus and other advanced area of math, this is a great app to have in your arsenal as well.(01-17-2016 08:30 AM)sbergman27 Wrote: It's been available for $19.99 for a while on Android now. You do only get 2D graphing capabilities, but you can graph all manner of trigonometric functions and equations. It does just about everything, with an easy-to-use and read graphing interface that's a perfect alternative to expensive devices. Quick graph has a 4-star rating in the App Store, with over 10,700 reviews, so it's definitely worth a download.Īnother free, full-featured calculator app, Calculator # is very well-reviewed on the App Store. You can then save your graphs to your photo library and share them at will. You can use wireframe or solid shapes in order to visualize your equations, and you can manipulate the image with everything from pinching to zoom to dragging and rotating.
You can plot six equations at the same in both 2D and 3D modes, though if you spend $2 and get the advanced feature set, that limit goes bye-bye. Quick Graph is a calculator app that's dedicated to graphing.
