WebHowever, there are two of these special cases when solving linear systems of equations. The first case occurs when solving the systems algebraically. The variables are eliminated, and the left side of the equation does not equal the right side of the equation. In this case there is no solution and the lines are parallel. Example-2x + 2y = 6-x ... Webalgebraically, that is, ... The Babylonians could have used the tables to solve cubic equations, ... (1540–1603) independently derived the trigonometric solution for the cubic with three real roots, and René Descartes (1596–1650) extended the work of Viète.

WebMar 2, 2024 · Explanation: If tanx = 1, then sinx = cosx. We know this is true for x = π 4 as a base case. Now, the tangent function is periodic with it's period. p = nπ, where n is an integer. So tanx = tan(x +nπ). Go back to the original equality : tanx = tan(x +nπ) = 1. The first positive value x0 for which tanx = 1 is, as stated before, π 4. Web$\begingroup$ What do you mean by "algebraically"? In the strictest sense, the word you are looking for is "transcendental" - meaning the solution is not the solution to any polynomial equation. However, $\sin(1)$ is a transcendental number, so this may be a broader category of things than you want. $\endgroup$ first touch football hull
