Prove that the semi-vertical angle of the right circular cone 4(x^2+y^2)-9z^2=0 is \tan^{-1}{3/2}.

The inverse tangent function, written as tan⁻¹(x) or arctan(x), determines the angle whose tangent is x. In simpler terms, if you know the ratio of the opposite side to the adjacent side of a right triangle, the arctangent will give you the angle.
