rigonometry comes from the Greek words that mean triangle measurement.
The six trig ratios or functions are dependent upon an angle "theta" (a letter from the Greek alphabet).
The six functions are:

Let's now use the above information to define the Six Trigonometric Functions in terms of a standard position angle q with point P and the terminal side of q.
