These are mostly pretty standard. LogX is useful when you have a number and you suspect it is a power ofÝ another known number, this will give the power. QEqN and QEqP are the two roots of the quadratic equation, if the root is imaginary, it returns an error. xSq, xSqR, and 1/x all just use the exponentiation operator, they are just convenience functions for use on buttons.
