This is because the hypotenuse is 1. This means that instead of turning into a ratio, sine and cosine just become a number that represents length. Example: Sin=opp/hyp. Because the hypotenuse is 1, sine is equal to the opposite.

If you are trying to find the trig ratio of a given angle and draw a right triangle with the right angle on the initial side, the side opposite the right angle, the hypotenuse,  is equal to the length of the radius--1. When trying to figure out the trig ratios, the implementation of the knowledge that the hyp equals 1 comes in handy. The sine value, opp over hyp, can be also be written as y over hyp, since the opposite side is vertical, but also could be further restated as y over 1, or simply y, because anything divided by 1 is just itself. The cosine value, adj over hyp, can be rewriiten as x over 1 or just x, since the adj side is horizontal, and corresponds to the x coordinate. Therefore, the sin and cos values in a unit circle are equal to the y and x values, respectively. The tan ratio, opp over adj, is the same as y over x (vertical and horizontal.)]]> 2017-03-13 02:30:46 UTC https://padlet.com/mann_lindsay/ebbpxq5ew5r4/wish/159556233 1002289 https://padlet.com/mann_lindsay/ebbpxq5ew5r4/wish/159557492 The hypotenuse of a reference triangle on the unit circle is always 1, and anything divided by 1 is itself.
