T.DIST(x, deg_freedom, cumulative)

The T.DIST function has the following arguments:

Argument Description
x The value at which the function should be calculated.
deg_freedom The number of degrees of freedom, an integer greater than or equal to 1.
cumulative A logical value (TRUE or FALSE) that determines the function form. If it is TRUE, the function returns the cumulative distribution function. If it is FALSE, the function returns the probability density function.
