Answer 1

$\star\:\:\:\bf\large\underline\blue{Question:-}$

• What is the value of $\sin360 \degree$

$\star\:\:\:\bf\large\underline\blue{Solution:-}$

$\sin360 \degree$

$= \sin2\times(180 \degree)$

Now, we know that

$\sin2 \alpha = 2 \sin \alpha \cos \alpha$

So,

$\sin2\times(180 \degree)$

$= 2 \sin180 \degree \cos180 \degree$

$= 2 (\sin (2 \times 90 \degree) )\cos180 \degree$

$= 2 \times 2 \sin90 \degree \times \cos90 \degree \times \cos180 \degree$

Now, we know that,

$\cos90 \degree = 0$

Sox

$= 2 \times 2 \sin90 \degree \times \cos90 \degree \times \cos180 \degree$

$= 0$

$\implies \sin360 \degree = 0$

$\star\:\:\:\bf\large\underline\blue{Answer:-}$

• $\sin360 \degree = 0$
