| 1 | Those are the equations we have to solve. | |
| 2 | And, in fact,something that is known as Maxwell's equations. | |
| 3 | Maxwell's equations were thus reduced to just two in number. | |
| 4 | All it could do, though, was solve those equations. | |
| 5 | The unknowns, in our equations, y will have to be a and b, not x and y. |
