ShearingMatrix[\[Theta], v, n] gives the matrix corresponding to shearing by \[Theta] radians along the direction of the vector v, and normal to the vector n.
ArcCosh
(Built-in Mathematica Symbol) ArcCosh[z] gives the inverse hyperbolic cosine cosh -1 (z) of the complex number z.
LogIntegral[z] is the logarithmic integral function li(z).
O
(Built-in Mathematica Symbol) O[x]^n represents a term of order x^n. O[x]^n is generated to represent omitted higher-order terms in power series. O[x, x_0]^n represents a term of order (x - x_0) n.
Sign
(Built-in Mathematica Symbol) Sign[x] gives -1, 0, or 1 depending on whether x is negative, zero, or positive.
