Type 9 nomogram code for Pynomo software. Projectile trajectory formula

This is a python-based code to be run under PyNomo software to construct a type 8 nomogram for projectile trajectory determination, that has the following expression:

\(y=x*\tan\alpha-{{g*x^{2}}\over{2*V_{0}^{2}*\cos^{2}\alpha}}\)

which can be represented under the determinant form satisfying type 9 nomogram.
