Cosecant, secant and cotangent are described as the reciprocals of the:
AFitted three functions
BFormal three functions
CFirst three functions
DFinest three functions
Answer & Solution
Correct answer: C. First three functions
1. Three further functions extend the basic three.
2. Each is one divided by an earlier one.
3. These functions are the reciprocals of the first three functions.
4. So the answer is the first three functions.
