Vector Tangent: A Challenge Problem

Write an algorithm that calculates the tangent of any arbitrary angle (in degrees) with the following restrictions:

The use of trigonometric functions is prohibited unless comparing the calculated value to the actual value returned by std::tan.
The use of the built-in square root function is prohibited.

Your solution must use vectors.

This was the prompt presented to me by a friend, my response to which is the program displayed above.

Building

This program can be built with g++.

g++ -o Vector-Tangent main.cpp Vector.cpp

Note: inputting unreasonably large numbers may cause undesired outputs due to the use of floating-point numbers.
