Question

the value of theta for which 2 sin^2 theta =1 is:?​

Answer 1

Answer:

45°

Step-by-step explanation:

Answer 2

Answer:

The answer is $\theta=45^\circ$

Step-by-step explanation:

Given  $2\sin^2\theta=1$

         $\Rightarrow \sin^2\theta=\dfrac{1}{2}\\\\\Rightarrow \sin\theta=\sqrt{\dfrac{1}{2}}=\dfrac{1}{\sqrt2}\\\therefore \theta=45^\circ$

• Since we know $\sin 45^\circ=\dfrac{1}{\sqrt 2}$
