Thread: 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.



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 ...



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