Step-by-step Solution
Specify the solving method
1
The angles where the function $\tan\left(x\right)$ is $1$ are
$x=45^{\circ}+360^{\circ}n,\:x=225^{\circ}+360^{\circ}n$
2
There is no identity or mathematical rule that allows us to proceed trying to match both sides of the equality, so we conclude that it is not true
The equation is not an identity
