##### 2 Answers

#### Explanation:

Recall the definitions of the reciprocal trig identities:

On the unit circle, the coordinates for

Where the

We can plug these values into our expressions for the reciprocal identities to get

Remember for

#### Explanation:

Draw a

Label the lengths of the sides and the degrees of the angles. Keep this drawing handy.

You should have these memorized:

**sine is opposite/hypotenuse
cosine is adjacent/hypotenuse
tangent is opposite/adjacent**

This question is asking for cot, csc and sec. Memorize these facts too:

**cosecant is 1/sine
secant is 1/cosine
cotangent is 1/tangent**

So thinking about the above things in bold,

Now look at your drawing of the
