R0...R9
Polar
Contains an expression in θ. In Symbolic view, select one of R0 through R9 and enter an expression.
In a program, type:
SIN(θ) R1
S1...S5
Statistics 2Var
The Statistics 2Var app variables are S1 to S5. These variables contain the data that dene a two-variable
statistical analysis. S1 returns a list of the objects that dene S1. Each list contains the following items, in
order:
An expression (in single quotes) that denes the independent variable data list (or empty double quotes)
An expression (in single quotes) that denes the dependent variable data list (or empty double quotes)
A string or expression that optionally denes the frequencies for the dependent data list
The t type number
The t expression
The scatter plot color
The mark type number for the scatter-plot point
The t plot color
The t type number is an integer from 1 to 13 that controls which statistical plot type is used with each of the
variables S1 to S5. The correspondence is as follows:
1—Linear
2—Logarithmic
3—Exponential
4—Power
5—Exponent
6—Inverse
7—Logistic
8—Quadratic
9—Cubic
10—Quartic
11—Trigonometric
12—Median-median line
13—User dened
The mark type number for the scatter-plot point is an integer from 1 to 9 that controls which graphic is used
to represent each point in a scatter plot. The correspondence is as follows:
