Answer :

Given:

To find: cos x and cot x



Since, x is in IIIrd Quadrant. So, sin and cos will be negative but tan will be positive.


We know that,


sin2 x + cos2 x = 1


Putting the values, we get


[given]








Since, x in IIIrd quadrant and cos x is negative in IIIrd quadrant



Now,



Putting the values, we get




= 2√6


Now,



Putting the values, we get



Hence, the values of other trigonometric Functions are:
