h[(tan-1(7.10/-3.52))]

h[(tan^-1(7.10/-3.52))]

$$\underset{\,\,\,\,^{\textcolor[rgb]{0.66,0.66,0.66}{360^\circ}}}{{tan}}^{\!\!\mathtt{-1}}{\left({\frac{{\mathtt{7.1}}}{-{\mathtt{3.52}}}}\right)} = -{\mathtt{63.628\: \!951\: \!849\: \!611^{\circ}}}$$

h[63.629°]     has no particular meaning to me
