KrAzY Posted October 31, 2013 Share #1 Posted October 31, 2013 Says my teacher! personaly I can figure out the decomposition rate of the suns molecules, but I can't remember how figure out sin, cos, or tan of a right or left triangle. anyone know a way for me to remember it?

Nate Posted October 31, 2013 Share #4 Posted October 31, 2013 sin and cosine always has the hypotenuese as the denominator sin is the opposite side over the hypotenuese cosine is the adjactent side over the hypoteneuese if you are stuck figureing out which one to use, remember that the sin of 90 degrees is 1 like if you want to force of gravity as you are going up a hill, use sine. A flat stretch of road needs no extra force, but to ride strait up a wall takes all you can possibly get Link to comment Share on other sites More sharing options...
kingtermite Posted October 31, 2013 Share #5 Posted October 31, 2013 sin and cosine always has the hypotenuese as the denominator sin is the opposite side over the hypotenuese (SOH) cosine is the adjactent side over the hypoteneuese (CAH) if you are stuck figureing out which one to use, remember that the sin of 90 degrees is 1 like if you want to force of gravity as you are going up a hill, use sine. A flat stretch of road needs no extra force, but to ride strait up a wall takes all you can possibly get Tangent is the opposite over the adjacent side. (TOA) Clarifying info added.

I'll try remembering all of that. 1 Link to comment Share on other sites More sharing options...
Nate Posted October 31, 2013 Share #7 Posted October 31, 2013 I had a problem remembering whether to use sin or cos when I was in high school, so my dad taught me how to think about it practically, and then its obvious which one you need well, obvious to the old man who was an engineer Link to comment Share on other sites More sharing options...
Indy Posted November 1, 2013 Share #8 Posted November 1, 2013 I'm an engineer, math is the only language I've ever been considered fluent in. How I remembered it, cosine already has an O in it. Tangent and Sine doesn't, they get their "O" first Opposite over Hypotenuse for Sine and Opposite over Adjacent for Tangent. Use the "O" as your key and you always have it.
