The Trigonometery functions in other presentation

  1. Aug 19, 2015 #1
    Can I present the trigonometry functions (such as SinX, CosX, TanX, CotX) by using only- Log, Lan, multiplication, division, addition, subtraction, exponantion, nth root operations?

    Using complex functions, you can represent [itex]sin(x)=\frac{e^{ix}-e^{-ix}}{2i}\ and\ cos(x)=\frac{e^{ix}+e^{-ix}}{2}[/itex].
