Question : $\sin ^4 \theta+\cos ^4 \theta$ in terms of $\sin \theta$ can be written as:

Option 1: $2 \sin ^4 \theta+2 \sin ^2 \theta-1$

Option 2: $2 \sin ^4 \theta-2 \sin ^2 \theta$

Option 3: $2 \sin ^4 \theta-2 \sin ^2 \theta-1$

Option 4: $2 \sin ^4 \theta-2 \sin ^2 \theta+1$

Team Careers360 20th Jan, 2024

Correct Answer: $2 \sin ^4 \theta-2 \sin ^2 \theta+1$


Solution : We know that, $\sin^2 \theta + \cos^2 \theta = 1$
⇒ $\cos^2 \theta = 1-\sin^2 \theta$
Now, $\sin^4 \theta + \cos^4 \theta$
$=(\sin^2 \theta + \cos^2 \theta)^2 - 2\sin^2 \theta \cos^2 \theta$
$=1^2 - 2\sin^2 \theta \cos^2 \theta$
$=1
