Introduction to basic trig functions

In any right angled triangle, for any angle:

The sine of the angle = the length of the opposite side   
                                         the length of the hypotenuse
sin x= O/H   
   
The cosine of the angle = the length of the adjacent side
                                             the length of the hypotenuse

cos x= A/H

The tangent of the angle = the length of the opposite side

                                               the length of the adjacent side

tan x= O/A
