simlin(a, b, c, d, e, f, g)
- a, b, c are numbers or expressions in terms of g, representing a line ax+by=c
- d, e, f are numbers or expressions in terms of g, representing a line dx+ey=f
- g is a variable name
Returns a list.
- 0th item is values of g for which the 2 lines intersect 0 times.
- 1st item is values of g for which the 2 lines intersect 1 time.
- 2nd item is values of g for which the 2 lines intersect ∞ times.
Example
