Question: In Example 1(d), change /6 to /3 and then evaluate tan 2/3. Data from Example 1(d) If = /6 we have tan = 12

In Example 1(d), change π/6 to π/3 and then evaluate tan 2π/3.


Data from Example 1(d)

If α = π/6 we have 

tan = 12 (7) tan 2 = 2 tan 1 - tan

tan = 12 (7) tan 2 = 2 tan 1 - tan (4) = 2(3/3) 1 - (3/3) = 3 using Eq. (20.25)
