There is more than one type of definition for the trig functions (they are all equivalent). Most of the above answers are refering to finding trig values when given a right triangle with a given angle. You can also find trig values by using points on the unit circle or even arbritrary points on a plane (where the point is on the terminal side of the angle in standard position). All definitions should be in your textbook or you could look online.

i will use x truly than theta to maintain typing... cos^2 x + sin^2 x = a million sin^2 x = a million - cos^2 x = a million - (36/60) = 24/60 = 4/10 sin x = 2/sqrt(10) = 2*sqrt(10)/10 =(a million/5)*sqrt(10) <<<

sin theta ,cos theta are the the coordinates on unit circle/
x=cos theta,y = sin theta
tan theta is y/x
cot theta is x/y

theta is just the name of the angle you are working with, and their values depend on the angle, or the length of the sides. soh cah toa

sin =oppositeside/hypothenuse
cos=base/hypothenuse
tan=oppositeside/base
cot=1/tan=base/oppositeside
cosec=1/sin=hypothenuse/oppositeside
sec=1/cos=hypothenuse/base

READ TRIGONOMETRY. THEY ARE RATIOS
