The most general value of

\theta

satisfying the equations

\sin \,\,\theta = \sin \,\,\alpha

and

\cos \,\,\theta = \cos \,\,\alpha

View answer and explanation

Correct option: C

n\pi + \alpha

Option A (

2n\pi + \alpha

) is correct because it represents the general solution where

\theta

and

\alpha

have the same sine and cosine values, indicating they are coterminal angles.
