- Triangular[ <Lower Bound>, <Upper Bound>, <Mode>, x ]
- Creates probability density function of triangular distribution with parameters min, max, mod.
- Triangular[ <Lower Bound>, <Upper Bound>, <Mode>, x, <Boolean Cumulative> ]
- If Cumulative is true, creates cumulative distribution function of triangular distribution, otherwise creates probability density function of triangular distribution.
- Triangular[ <Lower Bound>, <Upper Bound>, <Mode>, <Variable Value> ]
- Calculates the value of cumulative distribution function of triangular distribution at Variable Value v, i.e. the probability P(X≤v) where X is a random variable with triangular distribution given by parameters min, max, mod.
- Note: Returns the probability for a given x-coordinate's value (or area under the triangular distribution curve to the left of the given x-coordinate).

- Triangular[ <Lower Bound>, <Upper Bound>, <Mode>, <Variable Value>]
- Calculates the value of cumulative distribution function of triangular distribution at Variable Value v, i.e. the probability P(X≤v) where X is a random variable with triangular distribution given by parameters min, max, mod.
- Example:
Triangular[ 0, 5, 2, 2 ]yields 0.4.
