you can use the CAST rule.
please help me solve this i have a test tmr

-
tanθ = -7/24

tan^2(θ) = 49/(576)

sec^2(θ) - 1 = 49/576

sec^2(θ) = 625/576

sec(θ) = - 25/24 if θ is in II quadrant or 25/24 if it is in IV quadrant

cos(θ) = ±(24/25)

sin(θ) = SQRT[1 - 576/625]

sin(θ) = ± 7/25

csc(θ) = ±(25/7)
