-
- This program solves cubic equations.
-
- A cubic equation takes the general form
-
- Ax³ + Bx² + Cx + D = 0
-
- Enter the values for A, B, C, D into the writable icons in the
- "parameter" section of the window, then press return. The equation will then
- be solved and the roots displayed in the "solution" section of the window.
-
- ACCURACY
- ========
-
- The results are displayed to 4 places of decimals, but the fourth decimal
- place is not always reliable.
-
- In some cases an equation which really has three real roots will be reported
- as having one real and two complex roots, with the imaginary parts being
- 0.0000 and -0.0000. This is due to slight inaccuracies in BASIC real
- arithmetic.
