Cofunction Definition:
Trig measure for:
Angle complement: 90 - θ
Setup cofunction for sec(θ)
sec(θ) = csc(90° - θ)
Plug in θ = 60
sec(60) = csc(90° - 60)
sec(60) = csc(30)
Final Answer
sec(60) = csc(30)

What 7 formulas are used for the Cofunction Calculator?
sin(θ) = cos(90 - θ)cos(θ) = sin(90 - θ)
tan(θ) = cot(90 - θ)
csc(θ) = sec(90 - θ)
sec(θ) = csc(90 - θ)
cot(θ) = tan(90 - θ)
