Answer 1

Answer 2

sorry mis understood the quest
solve \[\sin \theta =\tan \theta \]

Answer 3

solve that equation to see what the answr would be
\[\sin\theta =\tan \theta \Longrightarrow \sin \theta =\frac{\sin \theta }{\cos\theta }\]

Answer 4

\[\sin \theta -\sin \theta\cos \theta =0 \Longrightarrow \sin \theta (1-\cos \theta )=0 \]

Answer 5

\[\sin \theta =0 ~~~or ~~~\cos \theta =1\]

Answer 6

when does sin equal zero
and when does cos equal 1

Answer 7

other way of doing this
take those options and plug them back to the equation
\[\sin \theta =\tan \theta \]
the first on does not work since tan is not defined for pi/2
the third left had side would not equal to right hand side so no
the D same as pi/2
so only B works
