Solution

Solution:

Cos(2) = -3/2

2 = Cos^-1(-3/2)

2 =(7+12K)/6 and (5 +12K) / 6

Now

=(7+12K)/12 and (5 +12K) / 12

Genral formula

Now for K = 0

=7/12 and 5 / 12

and for k= 1

=(7+12)/12 and (5 +12) / 12

and for k =2

=(7+24)/12 and (5 +24) / 12

(b)

from above

=(7+12K)/12 and (5 +12K) / 12

Now smaller

= (5 +12K) / 12
