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:
