determine the exact value of (cot pi/3) + (csc pi/3) / (cos pi/4). how is this calculated? i mean the steps to get the exact value?

• math -

all those angles are the standard ones you should know.

cot pi/3 = 1/√3
csc pi/3 = 2/√3
cos pi/4 = 1/√2

plug it in and you have

(1/√3 + 2/√3)/(1/√2)
= √6
