Usage

Type a string of letters into the textbox below, and watch the sequence change as you do! Possible sequence letters include:

L: Linear
Q: Quadratic
C: Cubic
U: Quartic
I: Quintic
G: Geometric
S: Sinusoidal
O: Cosinusoidal
H: Harmonic
F: Fibonacci
A: Factorial

For example, a quadratic sequence inside a linear sequence inside a cubic sequence will be written as "CLQ". You can think of the "reverse" order as being like a function, something like C(L(Q)), just with parentheses omitted.

You can also remove free variables by checking "Only significant".
