Periodicity Identities,degrees sin (x+ 2π) = sinx csc (x+ 2π) = cscx sin (x+ 360°) = sinx csc (x+ 360°) = cscx cos (x+ 2π) = cosx sec (x+ 2π) = secx cos (x+ 360°) = cosx sec (x+ 360°) = secx
Tan, cot, sec, and csc, calculated from trig identities. Once you know the value of sine and cosine, you can use the following trigonometric identities to obtain the values of the other four functions: Tangent is the sine-to-cosine ratio tan(α) = sin(α)/cos(α) Cosecant is the re...
