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

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