Answer:
[tex]\theta=\frac{3\pi}{4},\theta=\frac{7\pi}{4}[/tex]
Step-by-step explanation:
we are given
[tex]tan^{-1}(-1)[/tex]
Let's assume angle as theta
[tex]\theta =tan^{-1}(-1)[/tex]
so, we get
[tex]tan(\theta)=-1[/tex]
now, we can use unit circle and find theta
and we get
[tex]\theta=\frac{3\pi}{4},\theta=\frac{7\pi}{4}[/tex]
So, solution is
[tex]\theta=\frac{3\pi}{4},\theta=\frac{7\pi}{4}[/tex]
