Simult ax+by=c
| Given the coefficients a, b and c of
two linear equations, both in the form ax+by=c, this program will give the
point of intersection. |
|
 |
|
|
Simult y=mx+c
| Given the coefficients m and c of two
linear equations, both in the form y=mx+c, this program will give the
point of intersection. |
|
 |
|
|
y=mx+c (2pts)
| Given two points in the form (x,y),
this program will give the equation of the line passing through them. |
|
 |
|
|
y=mx+c (m&1pt)
| Given one point in the form (x,y) and a
gradient m, this program will give the equation of the line with that
gradient passing through the point. |
|
 |
|
|
Perp. bisector
| Given two points in the form (x,y),
this program will give the mid-point between them and the equation of the
perpendicular bisector. |

Simult 3x3
This program solves 3x3 systems of
simultaneous linear equations using a matrix (see also Matrices
section). The RREF function is used for this. (4,2,-3)
For example:
x+y=6
2x-z=11
3y+z=3 |
 |
 |
| If there is no solution or infinite
solutions to the system then the program reports this. For example,
changing the third equation to 2y+z=3 results in the "Infinite
solutions" message shown right, since it then becomes a linear
combination of the first two equations. |
