A simple expression i'm having trouble with because I have forgotten some basic rules to math.
"Find the exact value for each of the following expressions"
Sin(Pi/4)-Cos(Pi/6)+tan(Pi/3)
= sqrt2/2 - sqrt3/2 + sqrt3
This is where i'm stuck because I forget if you can multiply each term to have a common denominator. I ended up with:
sqrt2 + sqrt3 / 2
Help?
