Best ResponseYou've already chosen the best response.0Look at this link: http://en.wikipedia.org/wiki/Sine Particularly section "Relation to Unit Circle". In trignometry, sine and cosine are two basic functions. Their values are defined as ratios of sides of right triangle (formed inside the unit circle) based on various angle measures.

Best ResponseYou've already chosen the best response.0Really, first study that part and ask questions. If you understand this basic point, rest is all bunch of rearranging and playing with it.

Best ResponseYou've already chosen the best response.0In that above triangle sin(x) = a/c cos(x) = b/c In unit circle, c = 1 (radius of that unit circle).

Best ResponseYou've already chosen the best response.0tan is nothing but ratio of "sin and cos" tan = sin/cos

Best ResponseYou've already chosen the best response.0What function you solve for depends on the triangle's angles and measures in question. In my triangle above, x is the specific angle in the left bottom. If x was the right top angle, then sin and cos will "flip".

Best ResponseYou've already chosen the best response.0In general: sin = opposite side of angle / hypotenuse cos = adjacent side of angle / hypotenuse

Best ResponseYou've already chosen the best response.0sin(x) = a/c cos(x) = b/c tan(x) = sin(x)/cos(x) = a/c / b/c = a/b sin(y) = b/c cos(y) = a/c tan(y) = sin(y)/cos(y) = b/c / a/c = b/a
