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

sin is the opposite side over the hypotenuese (SOH)

 

cosine is the adjactent side over the hypoteneuese (CAH)

Tangent is the opposite over the adjacent side. (TOA)

Clarifying info added.

thanks... I'll try remembering all of that.

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

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.
