AB Trigonometric  functions  are  based  on  relationships  present  between  the  sides  and  angles  of  triangles.  Many  functions  are  derived  from  a  right  triangle—a  triangle  containing  a  right  (90˚)  angle.  Consider  the  right  triangle  below  with  sides  A,  B,  and  C,  and  angles  α,  β,  and  γ.
