Answer 1

any point on that unit circle (x,y) = (cos(t), sin(t))

Answer 2

since the hypotenuse is 1

Answer 3

Why did you make cos(t) negative?

Answer 4

you did all the work right, just use cos(t) as a positive value instead

Answer 5

the x coordinate of P is +

Answer 6

Thanks @DanJS! I corrected cos(t) to 15/17. Is that the only thing that I need to change?

Answer 7

hint:

tangent = sine/cosine

Answer 8

Wait, so would tan(t) be 8/15 then? @jim_thompson5910

Answer 9

tangent is positive, yes

Answer 10

cos is positive ---> sec is positive

tan is positive ---> cot is positive

Answer 11

the reciprocal identities have the same sign together

Answer 12

in a nutshell, everything is positive in Q1

Answer 13

+++!

Answer 14

I removed all the negatives and made them all positives, so I think I should be good. I think I may have misread something and thought one of the points was negative. Thanks for the help! :D
