Question

if sin 2theta =1 then theta = ____​

Answer 1

Answer:

Step-by-step explanation:

$sin^{2}A =1$( if the equation is this)

sin A=1

a=90

if equation=>  sin 2a = 1

2a=90

a=45

Answer 2

Answer:

30°

Step-by-step explanation:

sin2theta=1

sintheta=1/2

sintheta=30°sin

Sin will be cancelled from both sides

so,theta=30°
