# How do you find the exact value of tan^-1(1)?

${45}^{0}$

#### Explanation:

because you know that
$\tan \left(45\right) = 1$

so ${\tan}^{-} 1 \left(1\right)$equal to the $\theta$

which here equals to 45

so you are getting it by your background of the value of theta and just reverse, and I don't think there is a direct or simple way to do that.

or simply by using calculator
