Question

The statement "cot theta =12/5 , sec theta =-13/5 , and the terminal point determined by is in quadrant 4":
A. cannot be true because sec theta is greater than zero in quadrant 4.
B. cannot be true because 12^2+5^2 does not equal 1 .
C. cannot be true because cot theta must be less than 1.
D. cannot be true because if cot theta =-12/5 , then sec theta = is positive or negative 13/12 .

Answer 1

hints:

1) secant = 1/cosine

2) cosine is positive in this shaded region
