Today I little-known that the iPhone's deep-seated calculator app has a trig mode -- and all you need to do to derive it is turnover your roast on its side. If you're the type of person who keeps your roast permanently in portrait lock (like me), this might eventualize as a abruptness to you, as it did to plenteous of us here at The Verge.

This unlocks all sorts of functionality, like abacus numbers to memory, parentheses, exponents, and all those trig functions from rearward in high-reaching school. The full-length isn't exactly new, or hidden: It was outlandish in iOS 2.0 rearward in 2008, and there's convincingly plane a screenshot of it on the App Store page for the calculator app.
.. .To be fair, most persons most likely never see that App Store page, as the app comes pre-installed on every phone. It's not the first app that you'd most likely squinch for if you capital to install a new calculator, either -- plane with the hidden(ish) functionality, it's still not great.
For starters, there's no ticker tape feature, which lets you see all the operations you've just done, which is hospitable back you need to see if you've already boosted a value or not. It additionally makes some first-class functions like parentheses -- which I use in flukey every math equation I do -- impliable to access.
.. .Thankfully, there are other options: PCalc offers a other sarcous calculating experience, and offers a democratic PCalc Lite version that's additionally worth a download. Or for other strict math, there's the TI-30XS, which can make some things (like fractions) accordingly easy it flukey feels like cheating.
