    Simplify completely as possible

    Allright, moving along on the problems that I am working on, I have come across this:

    Q: Simplify as completely as possible.

    sin(π/3) //that is "pi" divided by 3 just in case the "pi" symbol isn't clear.

    So I am suppose to let π = 180˚ then divide by 3 thus giving me 60˚

    So I end up with sin(60˚) ?

    The book I am using mentioned how I can input this type of trigonometric function by entering it into a calculator.

    pi

    So I put (sin(π/3)) in the calculator and it gave me aprox. = .866025

    Any suggestions?


    Ohh how can I get the "pi" symbol using the math bracket code? I tried "p" and "i" encapsulated in math brackets but neither of those gave me the "pi" symbol.

    cheers.

    this is a unit circle value ...

    \sin\left(\frac{\pi}{3}\right) = \frac{\sqrt{3}}{2}

    learn the radian angles and their trig values on the unit circle ... today isn't too early to start.

    Many Ways To Solve

    The First Way is :

    <br />
 \sin \frac {\pi}{3} = \cos \frac {\pi}{6} = \sqrt {1-  \sin ^2 \frac {\pi}{3}}<br />

    Or You Can using Another One:

    <br />
\sin \frac {\pi}{3} = 2 \sin \frac {\pi}{6}\cos \frac {\pi}{6}<br />
