The Reciprocal Trig Ratios


*In addition to the three trig ratios covered so far (sine, cosine, and tangent), three other trigÌýratios are reciprocals of each of these ratios.
*They are:

Cosecant = hypotenuse opposite :

(This ratio (abbreviated csc) is the reciprocal of the sine function.)

Ìý

Cotangent = adjacent opposite :

(This ratio (abbreviated cot) is the reciprocal of the tangent function.)

Ìý

Secant = hypotenuse adjacent :

(This ratio (abbreviated sec) is the reciprocal of the cosine function.)
