Algebraic Functions

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.

Abs

 

 

Abs(value) =absolute value

Ln

 

 

Ln(value) = base e log of value

Log

 

 

Log(value) = base 10 log of value

LogX

 

 

LogX(X, value)

 

Ý= base X log of value

 

Power of X which = value

Perm

 

 

Perm(n, p)

 

= n things, p at a time

 

fails if (n-p) > 170

 

Permutations are number of

 

different sets where order

 

in set does count

Comb

 

 

Comb(n, p): n things, p at a time

 

Combinations are number of

 

different sets where order

 

in set doesn't count

Fact

 

 

Fact(value) = factorial of value

 

value <= 170, Fact(value <= 0) = 1

FMod

 

 

FMod(X, Y) = remainder

 

Floating remainder of X/Y

 

FMod(5.5, 2) = 1.5

QEqN

 

 

QEqN(a, b, c)

 

solution for ax^2 + bx + c = 0

 

for neg term in numerator

 

Fails for imaginaries

QEqP

 

 

QEqP(a, b, c)

 

solution for ax^2 + bx + c = 0

 

for sum term in numerator

 

Fails for imaginaries

xSq

 

 

square (^2)

xSqR

 

 

square root (^.5)

1/x

 

 

inverse (^-1)
