Question

Find the value of sin (1080), sin (1260)

Answer 1

$\underline{\textsf{To find:}}$

$\textsf{The value of}$

$\mathsf{sin\,1080^{\circ},\;sin\,1260^{\circ}}$

$\underline{\textsf{Solution:}}$

$\mathsf{Consider,}$

$\mathsf{sin\,1080^{\circ}}$

$\mathsf{=sin(3(360^{\circ})+0^\circ)}$

$\mathsf{=sin\,0^\circ}$

$\mathsf{=0}$

$\implies\boxed{\mathsf{sin\,1080^{\circ}=0}}$

$\mathsf{and}$

$\mathsf{sin\,1260^{\circ}}$

$\mathsf{=sin(3(360^{\circ})+180^\circ)}$

$\mathsf{=sin\,180^\circ}$

$\mathsf{=0}$

$\implies\boxed{\mathsf{sin\,1260^{\circ}=0}}$
