Remember the acronym Sohcahtoa.... it tells you what you need to do, know or compare to.
Sin=opposite side over hypotenuse (Soh)
Cos = adjecent side over hypotenuse (cah)
Tan = Opposite side over Adjacent (toa)

The are relationships of the lengths of the sides to the angle that forms them. If you know any two of the 3 parts of one of those equations, you can solve for the remaining piece.

The length of the days, plotted over time, makes a perfect sine-wave.

That's all the practical trig understanding I have. I knew all the college level calculations at one time, not clue one about what to do with it. It was a weed-out course, still have nightmares of "never went to class, time for the final".

Sine = opposite/hypotenuse
Cosine = adjacent/hypotenuse
Tan = opposite/adjacent

All you need to know about trig.

I used to to use it to figure out bolt hole patterns on the x and y axis.


When you want to correct a three axis MEMS magnetometer by way of an aligned three axis accelerometer to get a bearing when your instrument is tilted or rolled. Like when it's pointing at a drone that's carrying a grenade drop on you.

When you want to project a location from your current location in Lat and Lon from the previous derived bearing and a given distance.

When you want send a drone to that location because it is carrying a grenade drop on you.

Off the top of my head...

I could ask my 19-year-old grandson who got a perfect math score on the SAT, he'd know.

I used to know how to get someplace, but my phone got mapping software. But I can project that someplace on the earth in Lat and Lon.

This week I have been tapering my bull barrels down to sporter barrels.
The angle is so small, I cannot use the degrees scale on the compound. I have to use geometry.

The sine button on my calculator has dust on it.

Turn the crank for 3 hours and put 6 pounds of steel chips in the trash.

I Use trig and algebra all the time for construction math but I don't need to understand it to do it longhand on paper anymore.
I use a Jobber 6 calculator! The way God intended us to do trig/algebra.

That's enough to keep the buckethead coworkers away, they're allergic to math or learning!

The last several years it was A square +B square =C square to lay out foundations. An app on my phone does that now.

Odd, the ol' 'fire is, I'll ask a question, and think it will get some answers, and it won't, then again---.

Without know all about it, I think computer programs have taken over a lot of human thinking.

Your OP title says algebra, but post body asks trig......

So which is it?





I like trig.....
