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

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
