Question

cot 930 degree

Answer 1

v\Rotation twice is 360*2 = 720
So, you can subtract to make life easier: 930-720=210

That is cot 930 = cot 210

Now, 210 is in the 3rd quadrant. I have just as well subtract 210 - 180 = 30

Let us start with tan 30. You should get 1/ √3

Since tan is positive in the 3rd quadrant, tan 210 = tan 30 = 1/ √3

But you need cot 210

cot = 1/tan

So, cot 210 = 1/(1/ √3) = √3

Hence, cot 930 = cot 210 = √3
