Limit (Built-in Mathematica Symbol)

Limit[expr, x -> x_0] finds the limiting value of expr when x approaches x_0.

PolyGamma (Built-in Mathematica Symbol)

PolyGamma[z] gives the digamma function \[Psi](z). PolyGamma[n, z] gives the n\[Null]^th derivative of the digamma function \[Psi] (n) (z).

SetDelayed (Built-in Mathematica Symbol)

lhs := rhs assigns rhs to be the delayed value of lhs. rhs is maintained in an unevaluated form. When lhs appears, it is replaced by rhs, evaluated afresh each time.
