# If <span lang="EN

Given:  Since, θ is in IInd Quadrant. So, cos and tan will be negative but sin will be positive.

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

We know that,

sin2 θ + cos2 θ = 1

Putting the values, we get [from (i)]      Since, θ in IInd quadrant and cosθ is negative in IInd quadrant Now, Putting the values, we get   Now, Putting the values, we get  Now, Putting the values, we get  Hence, the values of other trigonometric Functions are: Rate this question :
