Remember all those cool functions you had in your HP-34C that didn't come with the 41C? Here they are. This is considered the essential add-on module, much like the TI-59's Master Library Module. Here we have matrix operations to order 14, an arbitrary function root finder, a polynomial solver/evaluator (to order 5), numerical integration, Complex arithmetic and functions, triangle solvers and (whoda thunk it) hyperbolic trig functions.

Functions:

• "MATRIX" Matrix data input routine
• "SIMEQ" Simutaneous equation solution
• "VCOL" ("SIMEQ") View column matrix
• "VMAT" ("MATRIX") View the matrix
• "PVT" ("MATRIX") Pivot a matrix that's already in memory
• "DET" ("MATRIX") Calculate determinant
• "INV" ("MATRIX") Invert the matrix
• "EDIT" ("MATRIX") Matrix element editor
• "SOLVE" Initialize function f(x) = 0 solver
• "SOL" ("SOLVE") Function solve subroutine
• "POLY" Initialize polynomial solver/evaluator
• "ROOTS" ("POLY") Polynomial solver subroutine
• "INTG" Numerical integration
• "DIFEQ" Differential equation solver
• "FOUR" Fourier expansion
• "C+" Complex add
• "C-" Complex subtract
• "C*" Complex multiply
• "C/" Complex divide
• "MAGZ" Magnitude of complex number, |z|
• "CINV" Reciprocal of complex number, 1/z
• "Z^N" Complex number to integer power
• "Z^1/N" Integer root of complex number
• "e^Z" e to the power Z
• "LNZ" Natural log of Z
• "a^Z" Real number to complex power
• "LOGZ" Log (input base) of Z
• "Z^W" Complex to complex power
• "Z^1/W" Complex root of complex number
• "SINZ" Sine of complex number
• "COSZ" Cosine of complex number
• "TANZ" Tangent of complex number
• "SINH" Hyperbolic sine
• "COSH" Hyperbolic cosine
• "TANH" Hyperbolic tangent
• "ASINH" Inverse hyperbolic sine
• "ACOSH" Inverse hyperbolic cosine
• "ATANH" Inverse hyperbolic tangent
• "SSS" Triangle Solution
• "ASA" Triangle Solution
• "SAA" Triangle Solution
• "SAS" Triangle Solution
• "SSA" Triangle Solution
• "TRANS" Coordinate transformation
• "*FN" (Support routine)
