The general value of

\theta

in the equation

\cos \,\,\theta = \frac{1}{{\sqrt 2 }},\,\,\tan \,\,\theta = - 1

View answer and explanation

Correct option: B

2n\pi \,\, \pm \,\,\frac{{7\pi }}{4},\;\,n \in I

Option B (

2n\pi \pm \frac{{7\pi }}{{4}},\;n \in I

) is correct because it represents the general solution for

\theta

that satisfies both

\cos \theta = \frac{1}{\sqrt{2}}

and

\tan \theta = -1
