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