| Waring also wrote on algebraic curves, classifying quartic curves into 12 main divisions with 84551 subdivisions. |
|
| Lagrange's main object was to find out why cubic and quartic equations could be solved algebraically. |
|
| Like Mazur, Pesic starts at the beginning with the irrationality of square roots and proceeds to the solution of cubic and quartic equations. |
|
| Ramanujan was shown how to solve cubic equations in 1902 and he went on to find his own method to solve the quartic. |
|
| MacMahon then worked on invariants of binary quartic forms, following Cayley and Sylvester. |
|
| The quartic in y must factor into two quadratics with real coefficients, since any complex roots must occur in conjugate pairs. |
|
| What are the general solutions to cubic and quartic polynomial equations? |
|
| Orthogonal contrasts were used to test linear, quadratic, cubic, and quartic effects of proportions of SFGS in diet substrates on rate of fermentation. |
|
| But if the double needle of the umbrella pine is equal to one phyllome we need only one quartic to describe the whole needle. |
|
| The most significant aspect of Waring's treatment of this example is the symmetric relation between the roots of the quartic equation and its resolvent cubic. |
|
| This came out of an investigation he was carrying out into when a ternary quartic form could be represented as the sum of five fourth powers of linear forms. |
|
| Thus, Galois perceived that solving equations of the quintic and beyond required a wholly different kind of treatment than that required for quadratic, cubic, and quartic equations. |
|
| A quartic kernel function using an adaptive bandwidth with a sample size of 15 burglaries and a cell size of 500m were selected. |
|
| The crucial step came in a book by a physician called Girolamo Cardano which presented formulas for both cubic and quartic equations. At this point, the future of algebra looked rosy. |
|
| In particular additive, quadratic, cubic and quartic functions are monomials of degree one, two, three and four respectively. |
|
| A quartic in age was included in the model as a demographic control. |
|
| In this work, a two step iterative formula is proposed in which the order of convergence is quartic. |
