Given:

Since, θ is in IVth 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 IVth quadrant and cosθ is positive in IVth 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:
