Question

Sin² 15° + cos² 15° find the value

Answer 1

Answer:

Sin²15° + Cos²15° = 1

Step-by-step explanation:

Because

Sin²x + Cos²x = 1

Answer 2

$\to$ 1

$\large \bold{ \underline{ \underline{ \: Explaination : \: \: \: }}}$

We know that ,

$\large{ \fbox{ \fbox{ { \sin^{2}} ( \theta) + { \ \cos^{2}} ( \theta) = 1}}}$

So ,

$\to$ Sin² 15° + Cos² 15°

$\to$ 1
