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

**Steve**, Wednesday, December 12, 2012 at 11:42am1. 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?
