A-2: Arithmetic Calculations



Example A-2.5

 Find exact and floating-point (decimal) values for each of the following: $\mathrm{sin}\left(\mathrm{π}/4\right)$, $\mathrm{cos}\left(1\right)$, $\mathrm{tan}\left(\mathrm{π}/12\right)$, ${\mathrm{sec}}^{-1}\left(2/\sqrt{3}\right)$

Note: The Maple names of the six trig functions are $\mathrm{sin},\mathrm{cos},\mathrm{tan},\mathrm{cot},\mathrm{sec},\mathrm{csc}$. The names of the six inverse trig functions are arcsin, arccos, arctan, arccot, arcsec, and arccsc. In math mode, ${\mathrm{sin}}^{-1}\left(x\right)$, etc., would be an equivalent notation for the inverse trig functions.
