N
(Built-in Mathematica Symbol) N[expr] gives the numerical value of expr. N[expr, n] attempts to give a result with n-digit precision.
Sec
(Built-in Mathematica Symbol) Sec[z] gives the secant of z.
TreeForm[expr] displays expr as a tree with different levels at different depths. TreeForm[expr, n] displays expr as a tree only down to level n.
ProbabilityDistribution[pdf, {x, x_min, x_max}] represents the continuous distribution with PDF pdf in the variable x where the pdf is taken to be zero for x < x_min and x > ...
