# If , find the values of all the other five trigonometric functions.

Given: sec x = -2 Given that: So, x lies in IIIrd Quadrant. So, sin and cos will be negative but tan will be positive.

Now, we know that Putting the values, we get …(i)

We know that,

cos2 x + sin2 x = 1

Putting the values, we get [given]      Since, x in IIIrd quadrant and sinx is negative in IIIrd quadrant Now, Putting the values, we get  =√3

Now, Putting the values, we get  Now, Putting the values, we get Hence, the values of other trigonometric Functions are: Rate this question :
