Question

find the general solution of sin2theata=1/2

Answer 1

Step-by-step explanation:

thithea =15. sin 2*15=1/2

Answer 2

I am taking symbol alpha instead of theta.

You probably mean this:

$sin(2 \alpha ) = \frac{1}{2} \\ = > sin(30) = \frac{1}{2} \\ = > 2 \alpha = 30 = > \alpha = 15$

You probably mean this also:

${sin}^{2} ( \alpha ) = \frac{1}{2} \\ = > sin( \alpha ) = \frac{1}{ \sqrt{2} } \\ = > sin(45) = \frac{1}{ \sqrt{2} } \\ = > \alpha = 45$

I hope it helped!
