Curious... do you know of a way to do quick ∆% calculations with either the Mac baked in calculator, spotlight Siri etc?
Thats something I'd use multiple times a day.
Excellent videos... Thanks Gary!
Bob: You'll need to describe what you want more than that. Give me an example.
On my M1 24" Mac, when I follow the formula you give for tan(45), it comes up with tan(45) = 1.619775... The answer should be 1. What's wrong?
Dan: If you just give it a number, it will assume radians. See the video. Use tan(45deg) or tand(45)
Thanks bunches
Please excuse my dear aunt Sally PEMDAS thanks for noting operation sequence
Hi Gary... ∆%, (or %CH) as often found on HP calculators. Say something was $69.99 yesterday & $49.99 today, it's a 28.58% reduction. It's easy enough to calculate manually, but if a Mac calculator/spotlight/Siri shortcut exists it would be nice; I do those calculations multiple times a day. Thanks!
Thanks, Gary. The "If you just give it a number, it will assume radians. See the video. Use tan(45deg) or tand(45)" works correctly. Something to note, the calculator in the M1 doesn't need the "deg" designation. Formula is "45, click tan, = 1" Interesting to say the least.
Bob: So just (69.99-49.99)/69.99 gives you that result. I don't think there is an easier way.
Dan: The Mac Calculator app, in Scientific mode, has a Deg/Rad button at the bottom left corner. So if you switch to degrees (in which case the button shows "Rad") then works that way, yes.
Good things to know. Thanx! Playing along with your video, discovered after entering a calculation in Spotlight, if I hit Return, it launches Calculator with the answer in it. Not sure how useful that is, but kinda neat.
Really helpful. Looks like a lot of these cool tricks are available, for what it's worth, using Spotlight on the iPhone, too.
