Almost everyday, sometimes hidden in the math. Rigid body motion has it baked in

I also teach FFTs and Fourier decomposition. The basis functions are sinusoids.

I teach computer vision, where it is inherent in the geometry of perspective projection.

Have you ever used sin, tan or cos in real life?

Huh?

OmahaThunderCoug

I have only really used sin.

RSL

6/16/21 11:54am

Some nice tans have caused me some sin

tan cos sin

Not always

mudpupper

6/16/21 12:27pm

ive used sin in a variety of ways. both good and bad.

Yes

Soh Cah Toa, maybe once a month.

when helping a middle schooler with geometry

johnnycarson

6/16/21 11:56am

yes. measuring straight-line distance using lat/long from 2 geographic points

LeonMarek

6/16/21 11:56am

This is where I used it for work. It was used for finding other nearby clients

Not often, but yes. Right triangle math is useful at times

rggee

6/16/21 11:56am

Yes sir (maam?). Pinball shot angles

TNT

6/16/21 11:56am

Yes, all the time when flying and weaponeering

I sin all the time and I tan at the beach but I'm not into cosplay.

Who doesn’t use these is the bigger question.

Texas Hammer

Absolutely, comes up often in engineering professions.

Is work 'real life' though?

rggee

6/16/21 12:02pm

Or if you've ever built something.

kccougar

6/16/21 12:05pm

Yep. pretty much literally every time I build something the basic

BYUMizzou

6/16/21 12:21pm

Yes, relatively frequently. All math has real life application somewhere.

MetaLearner

6/16/21 12:01pm

Yes, but I had to relearn it all for the job.

ReyOso

6/16/21 12:02pm

Yes, for sure, how else do you know how big of a box you need?

TomPetty

6/16/21 12:02pm

I use them all the time to figure out triangles and angles

Pangare

6/16/21 12:02pm

I know how to use them, just haven't ever used them.

I used COS to measure the height of some of our fir trees in our yard. We have 2 dozen+ fir trees in our yard. I was

Zenoch

6/16/21 12:04pm

Wouldn't that be TAN? Knowing the angle and the adjacent length, calc opposite

deejo

6/16/21 12:16pm

Whichever one it is. It's been several years since I did the calculations

Zenoch

6/16/21 12:32pm

All the time. It's basic geometry.

kccougar

6/16/21 12:04pm

Never. It's basic geometry.

They're embedded in everything around you.

whirl

6/16/21 12:04pm

Yeah, I built a bed and needed it to figure out an angle.

RyneK

6/16/21 12:06pm

All the time. I have to figure out the degrees of angles for work.

N8Dawg

6/16/21 12:07pm

A lot of my work is based on imaginary numbers and sin, cos, and Tan trig

novacoug1

6/16/21 12:13pm

imaginary numbers..... Do you work for a government finance agency?

Pangare

6/16/21 12:21pm

Of course. Quite a bit.

Northwest Cougar

6/16/21 12:13pm

Pretty often

Yes. I was building a ladder for a tree house ...

AggieWeekendCougar

6/16/21 12:38pm

YES, but kind of indirectly... Use FFT analysis alot, but honestly MATLAB is

Xenon

6/16/21 12:43pm

Yes, frequently. It helps in engineering.

thewaterboy

6/16/21 12:46pm

An unlikely use case for trig

TJ06

6/16/21 1:43pm

Nope, only when I get off on a tangent speaking...
