# The One Ring

## Great Circle Of Power, Math Student's Bane

Sixteen Marks for the fractions of pi,

Three Functions for the angles on a plane,

Three Co-functions for students to try,

Arc Functions for the inverse domain

In the study of Precalculus where the functions lie.

One Circle to rule them all, One Ring to find them,

Unit circle to calculate all, and in trigonometry bind them.

In the study of Precalculus where the functions lie.

This of course is a parody of the poem from the Lord of The Rings:

Three Rings for the Elven-kings under the sky,

Seven for the Dwarf-lords in their halls of stone,

Nine for Mortal Men doomed to die,

One for the Dark Lord on his dark throne

In the Land of Mordor where the Shadows lie.

One Ring to rule them all, One Ring to find them,

One Ring to bring them all and in the darkness bind them

In the Land of Mordor where the Shadows lie.
