The \emph{calculator trigonometric functions} are the basic trigonometric functions that appear on scientific and graphing calculators. These functions are $\sin$, $\cos$, and $\tan$. Knowing which of the trigonometric functions are the calculator trigonometric functions is useful for determining signs of trigonometric functions.
