After reconciling requirements, started work on quick solvers.
The plan is to implement at least:
- Quadratic equation solver,
- Cubic equation solver,
- Gain-offset solver,
- Generic root search (for any equation defined in program memory),
- Numeric integration (for any equation defined in program memory),
- Forward probability solver for normal distribution,
- Reverse probability solver for normal distribution.
Below is the approximate sequence for cubic equation Ax^3+Bx^2+Cx+D=0:
1. Enter A into T:, B into Z:, C into Y: and D into X: by any convenient method:
3. Read the result
