# TDIST

## Definition

### Sample Usage

`TDIST(A2, 30, 1)`

`TDIST(0.5, 1, 2)`

### Syntax

`TDIST(x, degrees_freedom, tails)`

`x`

- The input to the t-distribution function.`degrees_freedom`

- The number of degrees of freedom.`tails`

- Specifies whether the calculated distribution will be one- or two-sided. (1 for one-tailed distributions, 2 for two-tailed distributions).
