Question

Value of sin square theta

Answer 1

Step-by-step explanation:

here are some values of sin^2 a

......

${sin}^{2} \alpha \\ \\ = 1 - {cos}^{2} \alpha \\ \\ = \frac{1}{ {cosec}^{2} \alpha }$

Answer 2

Answer:

Step-by-step explanation:

sin^2 θ = 1- cos^2 θ

If θ = 30

Method 1

Then sin^2 30

= (1/2)^2 = 1/4

Method 2

Sin^2 30 = 1- cos^2 30

= 1-(root 3/2)^2

= 1-3/4

=1/4
