I just need help in how to start it.

**Anonymous**, Sunday, August 28, 2011 at 7:30pm8 sin^2(theta) + 2 cos^2(theta) = 6 sin^2(theta) + 2 [ sin^2(theta) + 2 cos^2(theta) ] =

6 sin^2(theta) + 2 [ sin^2(theta) + cos^2(theta) ]

Remark:

sin^2(theta) + cos^2(theta) = 1

6 sin^2(theta) + 2 [ sin^2(theta) + cos^2(theta) ] = 6 sin^2(theta) + 2 * 1 =

6 sin^2(theta) + 2

8 sin^2(theta) + 2 cos^2(theta) = 6 sin^2(theta) + 2 =

6 sin^2(theta) + 2 = a sin^2(theta) + b

Obviously:

a = 6

b = 2
