WebApr 11, 2024 · The string will then vibrate according to the wave equation ∂ 2 u/∂t 2 = 2 2 ∂ 2 u/∂x 2. Finally, we will also assume that when t = 0, ∂u/∂t = 0 for all values of x. This initial condition means that the string starts at rest. In terms of equations, we wish to solve the following initial-boundary value problem: WebIn mathematics, a linear equation in two variables is defined as an equation which should be of the form ax + by + c = 0, such that a and b is not equal to 0. Here a, b, c are the real numbers. This form of an equation is called the linear equation in two variables x and y.

WebSolving for a variable is also called isolating the variable, so you want to move everything away from it. To isolate y, first subtract 2x from both sides (4y = -2x + 100), then divide by 4 (y = -1/2 x + 25).
