Question

If sec = and the terminal point determined by is in quadrant 4, then:

sin theta = -2/5

cos theta = 3/5

csc theta = -5/4

tan theta = 4/3
all that apply??

Answer 1

sec theta = 5/3

Answer 2

Tan theta will be -4/3. since Tan is negative in quadrant 4.

Answer 3

sec = 1/cos

Answer 4

the option is 4/3 not - 4/3

Answer 5

So if you have the sec value, you just need to switch the numerator and denominator, and you'd get the cosine.

Answer 6

well then cos theta and sec theta are true. ans = B
