An example of an equation involving an absolute value sign looks like this: lx-5l=2. It can be solved by finding the numbers that will satisfy x-5=2 and x-5=-2, since l2l=2 and l-2l=2.
4 godz. temu · A good first step for solving the equation is to subtract 0.5 from both sides of the equation. A good first step for solving the equation is to split it into a positive case and a negative case. The positive case of this equation is 0.5 - |x - 12| = 0.25. The negative case of this equation is x - 12 = -0.75.

4 dni temu · The absolute value is a norm on the vector space formed by the real or complex numbers. The complex numbers form a one-dimensional vector space over themselve and a two-dimensional vector space over the reals; the absolute value is a norm for these two structures.
4 dni temu · The calculation of eigenvalues and eigenvectors is a topic where theory, as presented in elementary linear algebra textbooks, is often very far from practice. Classical method. The classical method is to first find the eigenvalues, and then calculate the eigenvectors for each eigenvalue.
5 dni temu · Find the Fourier series of \(f(x)=|x|\) on \([-\pi,\pi]\) and determine its sum for \(-\pi\le x\le\pi\). Solution: Since \(f\) is even and \(L=\pi\), \[F(x)=a_0+\sum_{n=1}^\infty a_n\cos nx.\nonumber \] Since \(f(x)=x\) if \(x\ge0\), \[a_0=\left. {1\over\pi}\int_0^\pi x\,dx={x^2\over2\pi}\right|_{0}^{\pi }={\pi\over2}\nonumber \] and, if \(n\ge1\),
