The invstudentst command computes the inverse of the cumulative probability density of the Students-t distribution with k degrees of freedom.

For example, invstudentst(2, 0.9) returns the value of x with probability equal to 0.9.

$\mathrm{MapleTA}:-\mathrm{Builtin}:-\mathrm{invstudentst}\left(2\,0.6\right)$

$0.288675134594813$

The MapleTA[Builtin][invstudentst] command was introduced in Maple 18.
