Aryabhata, the great mathematician of the classical age, invites you to test your math security skillz... His definitions of sine (jya), cosine (kojya), versine (utkrama-jya), and inverse sine (otkram jya) influenced trigonometry as a whole.

You will have to somehow create an equation that will elevate your status from a mere web user to a nodejs debugger.

You will have to use a version of chrome that is compatible (eg chrome 68.0.3440.84 (Official Build) (64-bit)) with the installed nodejs version.
