21. Trait?des substitutions et des �quations alg�briques ( Treatise on Substitutions and Algebraic Equations ). 22. For these types of disturbances Maxwell's equations transform into algebraic equations and are easily solved. 23. Solving differential equations is not like solving algebraic equations . 24. The five species model is based upon 5 ordinary differential equations and 17 algebraic equations . 25. The rational power of a complex number must be the solution to an algebraic equation . 26. The equation system can be resolved after " S ", resulting in a single algebraic equation : 27. This reduces the second differential equation to an algebraic equation which is much easier to solve. 28. The unknown coefficients \ alpha _ i can uniquely be determined by the above algebraic equation . 29. Polynomial transformations such as Tschirnhaus transformations are often used to simplify the solution of algebraic equations . 30. They are representative of differential and algebraic equations encountered in many branches of science and engineering.
