Asi o Mejor explicado? :)
The "Unit Circle" is a circle with a radius of 1.
Because the radius is 1, we can directly measure sine, cosine and tangent.

What happens when the angle, θ, is 0°?
cos 0° = 1, sin 0° = 0 and tan 0° = 0

What happens when θ is 90°?
cos 90° = 0, sin 90° = 1 and tan 90° is undefined

The "sides" can be positive or negative according to the rules of Cartesian coordinates. This makes the sine, cosine and tangent change between positive and negative values also.
