The value of

2\left(\sin ^6 \theta+\cos ^6 \theta\right)-3\left(\sin ^4 \theta+\cos ^4 \theta\right)+1

View answer and explanation

Correct option: B

Option B (0) is correct because by using trigonometric identities, the expression

2(\sin^6 \theta + \cos^6 \theta) - 3(\sin^4 \theta + \cos^4 \theta) + 1

simplifies to 0.
