1. If tanθ = –√3 , what is the value of cot ?
2. Find the value of 3sec2.4. (Round to the nearest tenth.)
7. if θ is a standard position angle and cotθ = 1.85, in which quadrant(s) could θ lie?
14.if sinθ = 4/5 and tanθ = 4/3, what is the value of cosθ ?
19. if tanθ = √33/4, use the fundamental identities to find sinθ < 0
please help me

1. cot = 1/tan
2. sec = 1/cos
7. tan,cot > 0 in QI,QIII
14. cos = sin/tan
19. 4^2 + (√17)^2 = (√33)^2, sin = tan*cos
so, what are your answers?

oops
19. 4^2 + (√33)^2 = (√49)^2
