# 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 $$\cot \angle CAB.$$
