Answer:
see below
Step-by-step explanation:
1/12 - 5/6 = -9/12
We need to get a common denominator of 12
1/12 - 5/6*2/2 = -9 /12
1/12 - 10/12 = -9/12
Since the denominators are the same, we can subtract the numerators
1-10 = -9
-9/12 = - 9/12
We can simplify -9/12 by dividing the top and bottom by 3
-9/3 = -3
12 /3 = 4
-9/12 = -3/4
Answer:

Step-by-step explanation:
The given angle is 240 degrees.
We need to find the exact value of each trigonometric function for the given angle θ.
Since
, it means θ lies in 3rd quadrant. In 3d quadrant only tan and cot are positive.






Therefore,
