That is an excellent, clear and concise explanation. I haven't done trig since high school back in the 70s. Of course in those days we didn't have calculators, we had little red books with pages of numbers for us to find the cos, sin and tan. I have bookmarked this video for later. Thank you
This is fantastic. I learned algebra and calculus but not trigonometry. Yet, triangles are a big component of many things that I deal with in building and sailing. Thank you!
I took trig in high school but my dumb ass didn’t pay attention and figured I’d never use it. Now I fabricate and build on the side and it sure would make life easier knowing it! Thank you my good sir.

The whole sin cos and tan seemed to make sense but once you added 3=6/2 (i have no idea where those numbers came from) i was lost. Maybe i'm below beginner. Cheers 4 sharing sir.
It is a shortcut for the algebra. You can use it as a quick reference to decide how you need to arrange the original formula to arrive at the correct answer.
You’re correct, it’s a way to simplify the algebra. It’s not redundant, because you would have to complete the algebra to isolate the variable regardless.
It is not completely redundant... when I was in school in 80's and 90's, we've had to demonstrate to the teacher (on the test), or to the class ( by the blackboard) that we know and understand the formula behind it.

I appreciate that very much, thank you.

Interesting that you learned Calculus before trig.
Thank you for teaching us this math formula.

I’ve heard that one before as well.
3=6/2 is a neat trick i hadn't seen before. I always did the pyramid thing I learned during trade school to do the same thing

Calculus next, please? 😊

I dont understand why you use the 3=6/2 step its redundant. If your trying to skip that algrabra i dont see how this helps. Good info anyways.
