This dot product calculator (2d) reference table shows the dot product for a range of vector a — x values, assuming a vector a — y of 4, a vector b — x of 2 and a vector b — y of 1. Every figure is computed with the same engine that powers our Dot Product Calculator (2D), so the numbers are exact.
| Vector A — x | Dot product |

| 0.75 | 5.5000 |
| 1.5 | 7.0000 |
| 2.3 | 8.6000 |
| 3 | 10.0000 |
| 4.5 | 13.0000 |
| 6 | 16.0000 |
| 9 | 22.0000 |
| 15 | 34.0000 |
| 21 | 46.0000 |
| 30 | 64.0000 |
How to use this table
Find the row closest to your vector a — x and read across to the dot product. For a value between two rows, the real figure sits between them — or enter your exact numbers in the Dot Product Calculator (2D) for a precise answer.
Need a value that is not in the table? — the Dot Product Calculator (2D) does it instantly, for free, with the formula and a worked example built in.
