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: Rate this question :
