\( \sin (^{2}x-3\cos (^{2}x=0)) \)

العبارة \( \frac{\sec \theta}{\csc \theta} \)

العبارة \( \frac{\sec \theta}{\tan \theta} \)

Use the statements below to find the size of angle \( x \). \[ \begin{array}{c}\text { Angle } x \text { is a multiple of } 12 . \\ \text { Angle } x \text { is acute. } \\ 2 \text { lots of angle } x \text { gives an obtuse angle. } \\ 3 \text { lots of angle } x \text { gives an obtuse angle. }\end{array} \]

Simplifica la expresion: \( \frac{\sin ^{2} \theta \cdot \sec \theta}{\tan \theta} \)
