1. If tan�θ = –√3 , what is the value of cot� ?

Question

2. Find the value of 3sec2.4. (Round to the nearest tenth.)

14.if sinθ� = -4/5 and tanθ� = -4/3, what is

Answer 1

cot = 1/ tan

2.4 degrees or 2.4 radians ?

sin = -4/5 so in quadrant 3 or 4
tan is negative so in quadrant 4
hypotenuse = 5
opposite = 4
adjacent = 3
so cos theta = 3/5
and theta = -53.1 or -.93 radians

Answer 2

1. -1/√3
2. Is the 2.4 in radians?
14. The question is incomplete.
Theta is in the fourth quadrant, sin^-1 4/5 below the +x axis.

Answer 3

1.) 1/root 3
