Verifying Identities
Verify that = is a solution:
sin + cos
sin = 1 + cot
Verify that = 30o is a solution:
(sec )(1 + cos ) = 1 + sec
Non-Permissible Values
Determine the non-permissible values of :
sin + tan
1+ cos = sin sec
sin cot
sec = cos2
On the interval 0 ≤ θ < 2π, identify the non-permissible values of θ for the trigonometric identity:
tan θ = 1cot θ
