Answer 1

Answer:

Hope this is helpful

Answer 2

Step-by-step explanation:

2sin²theta- cos²theta =2

=> 2 (1-cos²theta) - cos²theta = 2

=> 2-3cos²theta = 2

=> -3cos²theta = 0

=> cos²theta = 0

=> cos theta = 0

=> theta = (2n+1) π/2 , n€ I

or theta = π/2, 3π/2, 5π/2........

hope this helps you
