Answer:
- cos(θ) = -(√3)/2
- tan(θ) = -(√3)/3
Step-by-step explanation:
Referring to the attached short table of trig functions, we see that the reference angle with sin(θ) = 1/2 is π/6. The table also shows cosine and tangent values for that angle.
In the second quadrant, where π/2 < θ < π, the cosine and tangent are both negative. The values you seek are ...
cos(θ) = -(√3)/2
tan(θ) = -1/√3 = -(√3)/3
