Mathematics and Statistics Calculator

The Math/Stat calculator is designed to work with columns of data. In general the data is in the following format:

Input data format

For functions with two varibles (+, -, *, and /), the input data should be in two columns as (x₁, x₂). The result of the operations are x₁ + x₂, x₁ - x₂, x₁ * x₂, and x₁ / x₂, respectively.

For functions with one varible (i.e., cos( x ) ), the input data can be in one column or multiple columns. Results are displayed in a matrix form if the input data is in a matrix form.

For funtions with array variable (i.e, max( x ), std( x )), the input data in each column is an array.

Functions

+ plus: x1 + x2

- minus: x1 - x2

* time: x1 * x2

/ divide: x1 / x2

abs absolute value: |x|

acos arc cosine: acos(x)

asin arc sine: asin(x)

atan arc tangent: atan(x)

atan2(x2, x1) converts rectangular coordinates (x1, x2) to polar (r, theta)

ceil the smallest integer value that is not less than x: ceil(x)

cos the trigonometric cosine: cos(x)

E Euler's number e

exp Exponential function: exp(x)

floor the largest integer value that is not greater than x: floor(x)

inverse inverse: 1/x

mod(x, a) the remainder of x - n * a

ln the natural logarithm (base e): log_e(x)

log₁₀ the logarithm (base 10): log₁₀(x)

log_a the logarithm (base a): log_a(x)

max the greatest value in an array: max(x)

mean mean value of an array: mean(x)

min the smallest value in an array: min(x)

PI the constant Pi

power x to the a-th power: x^a

random random number between 0 and 1

round round to the coloses integer: round(x)

round2 round to the a-th decimal point: round(x, a)

std standard deviation of an array: std(x)

std_N-1 bias-corrected standard deviation of an array: std_N-1(x)

sin the trigonometric sine: sin(x)

sqrt positive square root: sqrt(x)

sum sum of an array: sum(x)

tan the trigonometric tangent: tan(x)

toDegrees converts an angle measured in radians to degrees

toRadians converts an angle measured in degrees to radians

var variance of an array: var(x)
