Sin Cos Tan??

[SuckAtMath]

Some1 please help with explaining the sin cos tan rule. I'm going to take a SAT test and (unfortunately) it includes a rather difficult sin problem. And my brain decided to bust on me again. =.=

1) Change your screen name. Really...

2) There are at least three definitions. Which do you want? Just memorize the relationships in a RIGHT triangle.

Find a right triangle. Pick an acute angle. Call it 'a'.

cos(a) = Adjacent leg length / hypotenuse length

sin(a) = Opposite leg length / hypotenuse length

tan(a) = Opposite leg length / Adjacent leg length = sin(a) / cos(a)

Memorize. Focus. Don't waste any more time telling yourself that you can't do it.

What do you mean, specifically, by "the sin cos tan rule"? Which "rule" (property? identity? definition?) do you have in mind?

Thank you!

… a rather difficult sin problem …

May we see this exercise? Perhaps, it is not as difficult as you think. :cool:
