11 detalles sobre LinearSystemsSolver

1. For example, to solve the system 3a+5b=1, -2a-11b=7, 5a+4b=6, enter the number of equations, 3, the number of variables, 2, or 3,2, followed by the coefficients and constants 3,5,1,-2,-11,7,5,4,6, (note the commas and the position of the righthand constants 1, 7 and 6).

2. To solve systems of linear equations enter the number of equations (an integer between 2 and 23 inclusive) then a comma, then enter the number of variables (an integer between 2 and 23 inclusive) then a comma.

3. Press the Clear button to edit the number of equations or variables, to solve another system or when exiting the app.

4. To edit the coefficients of a constraint, enter coefficients and right-hand constants (under A, B, and C), then tap the colored box for that constraint to input.

5. Enter the coefficients of each equation and their righthand constants in order of appearance from left to right; separate each coefficient, righhand constant and equation with a comma.

6. The user is provided with a keypad, a two-line text field for input, a help window briefly describing the app’s operation and a solution box where warnings (in red), messages and solutions appear.

7. P-values at corner points are below P in order of Solve output or in the constraint boxes.

8. To find corner points, tap X and Y in Intercepts for each constraint's colored box, then tap Solve, Solve1, Solve2 etc.

9. Press or hold the right or left arrows or Del only to edit coefficients and constants.

10. Enter the objective function P: tap the box below A; enter a number using the number pad.

11. To solve the system 4a+3b=1, -2a-9b=2, we enter 2,2,4,3,1,-2,-9,2 in the textfield.
