Question

if theta is equals to 30 find the ratio 2 Sin Theta into sin 2 theta​

Answer 1

Answer:

Step-by-step explanation:

θ=30

so 2sinθ × sin2θ

=2sin 30 × sin 2×30

=2×1/2×sin 60

=1×√3/2

=√3/2

Given:-

$\theta = 3 {0}^{0}$

Find:-

$2 \: sin \: \theta \ratio sin \: 2 \: \theta$

Solution:-

$2 \: sin \: 3 {0}^{0} \ratio sin \: 2(3 {0}^{0})$

$2 \: sin \: 3 {0}^{0} \ratio sin \: 6 0^{0}$

$2( \frac{1}{2} ) \ratio \frac{ \sqrt{3} }{2}$

$1 \ratio \frac{ \sqrt{3} }{2}$

$\therefore2 \ratio \sqrt{3}$
