If and θ lies in Quadrant IV, find the values of all the other five trigonometric functions.

Given:

Since, θ is in IV^th Quadrant. So, sin and tan will be negative but cos will be positive.

We know that,

sin² θ + cos² θ = 1

Putting the values, we get

[given]

Since, θ in IV^th quadrant and cosθ is positive in IV^th quadrant

Now,

Putting the values, we get

Now,

Putting the values, we get

= -2

Now,

Putting the values, we get

Now,

Putting the values, we get

=-√3

Hence, the values of other trigonometric Functions are:
