Use iPhone’s Secret Scientific Calculator

Assistant Editor

We don’t really know how to find the sine of an angle in a right triangle, but we can tell you where to go on your iPhone to do it.

If you open Apple’s built-in calculator app, you’ll find basic functions for adding and multiplying and such. But tilting your iPhone into landscape mode will expand the app to show scientific calculator functions. Sine, cosine, log, exponents — they’ve all been there right under your nose this whole time!

So there you go. If you didn’t already know that you can “count” on Yahoo Tech for quick and useful gadget tips, you should now.
