IB MS I 3 MORE Trig Functions?! WS Name: ____________________________ In addition to sine, cosine, and tangent, there are three other trigonometric functions you should know about: cosecant, secant, and cotangent. These functions are simply the reciprocals of sine, cosine, and tangent. 1

values of all 6 trig functions. Don’t forget to rationalize denominators and simplify!
sin θ = ________
csc θ = ________
cosθ = ________
secθ = ________
tan θ = ________
cot θ = ________
