Use an addition or subtraction formula to write \[ \frac{\tan 39^{\circ}+\tan 24^{\circ}}{1-\tan 39^{\circ} \tan 24^{\circ}} \] as a trigonometric function of one number.

\( r = \tan \theta \sec \theta \)

\( \operatorname{Csc} 82.4^{\circ}= \) Blank 1 Express your answer in 3 decimal points.

i) \( \frac{\tan \theta \cot \theta}{\sec \theta} \) equals: A \( \sin \theta \)
