NFourierCosCoefficient[expr, t, n] gives a numerical approximation to the n\[Null]^th coefficient in the Fourier cosine series expansion of expr, where expr is a periodic ...
NFourierSinCoefficient[expr, t, n] gives a numerical approximation to the n\[Null]^th coefficient in the Fourier sine series expansion of expr, where expr is a periodic ...
Due to the complex inner workings of the Notation Package it is helpful to outline some of the more advanced features and structures of the Mathematica front end and how they ...
BaseForm[expr, n] prints with the numbers in expr given in base n.
GeometricTransformation[g, tfun] represents the result of applying the transformation function tfun to the geometric objects corresponding to the primitives ...
MapThread[f, {{a_1, a_2, ...}, {b_1, b_2, ...}, ...}] gives {f[a_1, b_1, ...], f[a_2, b_2, ...], ...}. MapThread[f, {expr_1, expr_2, ...}, n] applies f to the parts of the ...
MathMLForm[expr] prints as a MathML form of expr.
MatrixRank[m] gives the rank of the matrix m.
Min
(Built-in Mathematica Symbol) Min[x_1, x_2, ...] yields the numerically smallest of the x_i. Min[{x_1, x_2, ...}, {y_1, ...}, ...] yields the smallest element of any of the lists.
NullSpace[m] gives a list of vectors that forms a basis for the null space of the matrix m.
