The Linear Solver app has a single function that solves a
2x2 or 3x3 linear system, based on a matrix of
coefficients and constants.
LinSolve
Solve linear system. Solves the 2x2 or 3x3 linear system
represented by matrix.

Triangle Solver
app functions
The Triangle Solver app has a group of functions which
allow solving a complete triangle from the input of 3
consecutive parts of the triangle. The names of these
commands use A to signify an angle, and S to signify a
side length. To use these commands, enter 3 inputs in the
specified order given by the command name.

Returns a list of three results that correspond to the
opposite angle or side from the given input. If the input
given was an angle, the item in same position in the
results list will be the opposite side.
Example:
In Degree mode,
SAS
(
2, 90, 2
) returns { 45, 2.82…,45}.
