Question

if sin theta = cos theta then find the value of theta​

Answer 1

Answer:

when sin 45 and cos 45

then sin theta =cos theta

so,theta=45°

Answer 2

Answer:

45°

Step-by-step explanation:

• let theta be alpha

$\sin( \alpha ) = \cos( \alpha ) \\ \frac{ \sin( \alpha ) }{ \cos( \alpha ) } = 1 \\ \tan( \alpha ) = 1 \\ \tan( \alpha ) = \tan(45) \\ \alpha = 45$
