Trigonometric Functions

SOH-CAH-TOA! Have you heard the call of the trig function? Use them to navigate the trickier sides (and angles) of geometric shapes.

Reciprocal Trigonometric Functions

         

Which of the following is equal to

\[ \frac{ 1} { \sin \theta }? \]

Which of the following is equal to

\[ \frac{ 1} { \cos \theta }? \]

Which of the following is equal to

\[ \frac{ 1} { \cot \theta }? \]

If \(0^\circ < \theta < 90^\circ,\) what is the minimum possible value of \[\left(\sin(\theta) + \cos(\theta)\right) \cdot \left(\csc(\theta) + \sec(\theta)\right)?\]

In a right triangle \(ABC,\) \(AB=7,\) \(BC=24,\) and \(CA = 25.\) Find \(\cot \angle CAB.\)
