yeah and also cot(theta) is negative in quadrant IV

jim_thompson5910 · Answer

and if cot(theta) = 12/5, then sec(theta) = 13/12

so everything is just off on this problem

kj4uts · Answer

ok so it is d. im still a little confused on how to know this

jim_thompson5910 · Answer

you have to know that sec(theta) = 1/cos(theta)

jim_thompson5910 · Answer

and where cosine is positive and negative

jim_thompson5910 · Answer

that helps you determine the sign for secant

kj4uts · Answer

oh ok so answer: D so the 4th. Q, cosines is +, therefore sec. must be +

jim_thompson5910 · Answer

yes

kj4uts · Answer

ok thank you again for your help
