Triangular( <Lower Bound>, <Upper Bound>, <Mode>, x )
Creates probability density function of triangular distribution with parameters lower Bound, upper Bound, Mode.
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 lower Bound, upper Bound, Mode.
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).
Example: Triangular(0, 5, 2, 2) yields 0.4.
