tan^(-1)*5

$$\underset{\,\,\,\,^{\textcolor[rgb]{0.66,0.66,0.66}{360^\circ}}}{{tan}}^{\!\!\mathtt{-1}}{\left(-{\mathtt{1}}\right)} = -{\mathtt{45^{\circ}}}$$

I am not sure what that is meant to be.

Maybe

$${\mathtt{atan5}} = \underset{\,\,\,\,^{\textcolor[rgb]{0.66,0.66,0.66}{360^\circ}}}{{tan}}^{\!\!\mathtt{-1}}{\left({\mathtt{5}}\right)}$$

$$\underset{\,\,\,\,^{\textcolor[rgb]{0.66,0.66,0.66}{360^\circ}}}{{tan}}^{\!\!\mathtt{-1}}{\left({\mathtt{5}}\right)} = {\mathtt{78.690\: \!067\: \!525\: \!98^{\circ}}}$$
