Jul 10, 2020 · The ${\tan(x)}$ function is periodic, meaning it will not be injective, thus will not have an inverse. Unless you restrict the domain. For example, in your case $${\tan\left(\frac{25\pi}{4}\right)=\tan\left(\frac{\pi}{4}\right)}$$ So if you apply the inverse function - what value do we take?
