Expert Solution
Step 1

we have to list the angles in terms of π6,π4&π3 from any quadrant that can be used as a sum or difference for π12

Step 2

if we take 2π3 & 3π4 and subtract it we get 

3π4 -2π3=9π-8π12=π12

now taking 4π3 & 5π4

4π3 -5π4=16π-15π12=π12

taking 5π3 & 7π4

7π4 -5π3=21π-20π12=π12
