168 Functions and commands
Example:
DoFinance(FV) returns the future value of an investment in
the same way as tapping in the Numeric view of the
Finance app with FV highlighted.
Linear Solver app functions
The Linear Solver app has 3 functions that offer the user
flexibility in solving 2x2 or 3x3 linear systems of equations.
Solve2x2 Solves a 2x2 linear system of equations.
Solve2x2(a, b, c, d, e, f)
Solves the linear system represented by:
ax+by=c
dx+ey=f
Solve3x3 Solves a 3x3 linear system of equations.
Solve3x3(a, b, c, d, e, f, g, h, i, j, k, l)
Solves the linear system represented by:
ax+by+cz=d
ex+fy+gz=h
ix+jy+kz=l
LinSolve Solve linear system. Solves the 2x2 or 3x3 linear system
represented by matrix.
LinSolve(matrix)
Example:
LinSolve([[A, B, C], [D, E,F]]) solves the linear system:
ax+by=c
dx+ey=f
Triangle Solver app functions
The Triangle Solver app has a group of functions which allow
you to solve a complete triangle from the input of three
consecutive parts of the triangle (one of which must be a side
length). The names of these commands use A to signify an
angle and S to signify a side length. To use these commands,
enter three inputs in the specified order given by the
