csolve_n.zip278k11-04-24File is not ratedSolve n x n Systems of Non-Linear Equations
This new version of cSolve_n() finds real and complex solutions of n x n systems of non-linear equations. Some trig equations can be handled, but no more than one unknown angle. The number of equations is no longer limited to 3 and unknowns are not limited to x, y, and z. The program is basically a version of the TI Solve and cSolve functions, but is easier to use (no variable list to enter). Domain restrictions, such as x > 0 or θ > -π and θ ≤ π, can be entered. All entries can be edited. If there are more unknowns than equations, you can choose which to solve for, so symbolic solutions can be found.

This is an update of Mtrxedtr(). This program is a matrix editor, which I use as an alternative to the TI-89 Data/Matrix Editor. I use it as a keyboard program so it's easier to access and use than the Data/Matrix Editor. You can create and edit a matrix, edit an existing matrix, insert rows or columns, and check dimensions easily even when the matrix is too large for the screen. You don't have to name the matrix before it is created so you save a few steps and time. The matrix is automatically saved as "z", unless you choose to change it. This update improves the editing process and changes the display to allow you to scroll through a large matrix.

simul_mn.zip7k04-02-27File is not ratedSimultaneous Linear Equation Solver
This program provides modified input, output, and editing systems for the TI Flash Apps Simultaneous Equation Solver. This update addresses 2 problems. 1. The lockup problem sometimes encountered when using complex coefficients in the Apps program. In Simul_mn() v. 1.2, complex coefficients can be now entered in either polar or rectangular form. Results can be toggled between polar and rectangular. 2. The alpha lock problem which occurred ( even with autoaoff() installed ) when the program was run by using Catalog, F4. Alpha lock now remains off. Results are copied to the home screen. Results and the original augmented matrix are saved automatically. This eliminates the bother of naming a variable each time you save results. Coefficients can be entered directly or as a previously stored augmented matrix. Coefficients can be edited by rows. Results can be toggled between auto or approximate form. Solutions to dependent systems are given in terms of arbitrary constants. To use Simul_mn(), you must have TI Flash Apps Simultaneous Equation Solver installed on your calculator.

To simplify keystrokes, that is, to avoid hunting for the angle symbol, Ð, polar form is entered as r,,q and rectangular components as x,y. Note the use of 2 commas instead of , Ð in polar form. Entries can be edited. As each vector is entered, the sum of all vectors entered to that point is displayed. Subtraction can be included by entering the magnitude as a negative quantity. Results are copied to the home screen in both forms. This update also addresses the alpha lock problem which occurred ( even with autoaoff() installed ) when the program was run by using Catalog, F4. Alpha lock now remains off.

This is a program which calculates and diagrams the sum of any number of 2-dimensional vectors. This update allows the input of vectors (or complex numbers) in either polar or rectangular form. To simplify keystrokes, that is, to avoid hunting for the angle symbol, Ð, polar form is entered as r,, q and rectangular components as x,y. Note the use of 2 commas instead of , Ð in polar form. Entries can be edited. Results are copied to the home screen in both forms. After all vectors are entered, the vector sum is displayed and two types of vector diagrams are drawn. The first diagram displays each of the vectors in standard position at the origin. The second diagram is the vector polygon formed by the vectors and their resultant. The vector sum is copied to the home screen.
vec_non3.zip19k06-10-15File is not ratedSolve Systems of Non-Linear Equations & 2-D Vector Equation
This update changes Vec_non3() so that it now just calls up Solvnon3() or Vec2d_eq() to solve systems of non-linear equations or 2 dimensional vector equations. This results in the vector part being easier to use. It solves vector equations (with no more than one unknown angle). It finds real solutions of n x n systems of simultaneous, non-linear equations, for n=1,2,3. It can handle various types of equations, including trigonometric equations (with no more than one unknown angle). The unknowns must be represented by x, y, and z. Any unknown angle must be represented by x. The domains of x, y, and z can be set as desired. For angles, the default domain is 0 to 2pi, but can be set by quadrants, or any values you want. Solutions are copied to the home screen, so they can be more easily used in further calculations.
