Question

if sin square theta = 1/2 then find the value of cos square theta​

Answer 1

Answer:

Step-by-step explanation:

Sin sq.theetha = 1/4

Cos sq.theetha = 1-sin sq. Theeta

=1-1/4

=3/4

Answer 2

The relationship is as follows :

Cos squared theta + Sin squared theta = 1

In other words we can say :

1 - Sin squared theta = Cos squared theta.

This relationship will help us solve the equation.

Now since :

Sin Squared theta = 1/2 then :

Cos squared theta = 1 - Sin squared theta.

This equals :

1 - 1/2 = 1/2

= 0.5

Cos squared theta is thus :

0.5
