| 1. | It is not known how Brahmagupta arrived at his interpolation formula.
|
| 2. | This formula is called the Fuchs-Sutugin interpolation formula.
|
| 3. | This is an implementation of the Whittaker Shannon interpolation formula.
|
| 4. | Gou derived a cubic interpolation formula for his astronomical calculations.
|
| 5. | This is Stirling's interpolation formula truncated at the second-order differences.
|
| 6. | :Conceptually the simplest way to figure out that summation is through the Lagrange interpolation formula.
|
| 7. | For a more practical approach based on band-limited signals, see Whittaker Shannon interpolation formula.
|
| 8. | Applying the Lagrange interpolation formula to do quadratic interpolation on the inverse of " f " yields
|
| 9. | (also derived earlier, as mentioned above ) and the Brahmagupta interpolation formula for computing sine values.
