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
specied order given by the command name. These commands all return a list of the three unknown values
(lengths of sides and/or measures of angles).
AAS
Angle-Angle-Side. Takes as arguments the measures of two angles and the length of the side opposite the
rst angle and returns a list containing the length of the side opposite the second angle, the length of the
third side, and the measure of the third angle (in that order).
AAS(angle,angle,side)
Example:
AAS(30, 60, 1) in degree mode returns {1.732…, 2, 90}
ASA
Angle-Side-Angle. Takes as arguments the measure of two angles and the length of the included side and
returns a list containing the length of the side opposite the rst angle, the length of the side opposite the
second angle, and the measure of the third angle (in that order).
ASA(angle,side,angle)
Example:
ASA(30, 2, 60) in degree mode returns {1, 1.732…, 90}
