How do I solve:(adsbygoogle = window.adsbygoogle || []).push({});

[sin (pi/3)] + [cos (pi/6)]? <--- "pi" is 3.14......

I think that [sin (pi/3)]= (square root 3) divided by 2

AND that [cos (pi/6)]= (square root 3) divided by 2.

Now I can't remember how to add fractions containing square roots.

My textbook says the answer is: square root 3.

I just have NO IDEA how to get there.

Please help! Thanks in advance.
