al@19849 | 1 Mathomaticâ„¢ is a free and open source command-line computer algebra system (CAS) |
al@19849 | 2 for doing floating point calculations and symbolic mathematics. It can |
al@19849 | 3 automatically solve, simplify, combine, and compare algebraic equations, do some |
al@19849 | 4 calculus, etc. |
al@19849 | 5 |
al@19849 | 6 ``` |
al@19849 | 7 1-> x^2 + 4x - 21 = 0 |
al@19849 | 8 |
al@19849 | 9 #1: x^2 + (4*x) - 21 = 0 |
al@19849 | 10 |
al@19849 | 11 1-> solve x |
al@19849 | 12 Equation is a degree 2 polynomial equation in x. |
al@19849 | 13 Equation was solved with the quadratic formula. |
al@19849 | 14 Solve successful: |
al@19849 | 15 |
al@19849 | 16 #1: x = -(2 + (5*sign)) |
al@19849 | 17 |
al@19849 | 18 1-> calculate |
al@19849 | 19 There are 2 solutions. |
al@19849 | 20 |
al@19849 | 21 Solution number 1 with sign = 1: |
al@19849 | 22 x = -7 |
al@19849 | 23 |
al@19849 | 24 Solution number 2 with sign = -1: |
al@19849 | 25 x = 3 |
al@19849 | 26 1-> |
