Question

sin 1200 convert and say answer

Answer 1

heya

As you know that when sin is in the form of (N×360°+¢) =sin¢ this funda is use here

=)sin(360°×3+120°)

=Sin120°

=sin(90°-30°)

=cos30°

=√3/2 Ans


hope it help you

Answer 2

Answer:

The value of sin 1200 = $\frac{\sqrt{3} }{2}$

Step-by-step explanation:

To find,

The value of sin1200

Recall the formulas

$sin (nX360 +\theta) = sin\theta$

sin(90+$\theta$) = cos$\theta$

Solution:

sin 1200 = sin (1080+120)

=sin(3X360 +120)

=sin 120(since $sin (nX360 +\theta) = sin\theta$)

sin 1200 = sin 120

sin 120 = sin(90+30)

= cos 30 (since sin(90+$\theta$) = cos$\theta$)

= $\frac{\sqrt{3} }{2}$

sin 120 = $\frac{\sqrt{3} }{2}$

sin 1200 = $\frac{\sqrt{3} }{2}$
