Hace 3 días · For stability the ROC must contain the unit circle. If we need a causal system then the ROC must contain infinity and the system function will be a right-sided sequence. If we need an anticausal system then the ROC must contain the origin and the system function will be a left-sided sequence.
Hace 2 días · Schrödinger's equation inscribed on the gravestone of Annemarie and Erwin Schrödinger. ( Newton's dot notation for the time derivative is used.) The Schrödinger equation is a linear partial differential equation that governs the wave function of a quantum-mechanical system.
Hace 5 días · Unit circle definitions. In trigonometry, a unit circle is the circle of radius one centered at the origin (0, 0) in the Cartesian coordinate system. Unit circle: a circle with radius one. Let a line through the origin intersect the unit circle, making an angle of θ with the positive half of the x-axis.
Hace 4 días · Since p(x) and q(x) are already expanded in power series, and these series are not infinite, the radius of convergence for them is ρ = ∞. Therefore, the series solution about x 0 = 0 must have a radius of convergence that is at least as large as ρ = ∞, which of course means it must be ρ = ∞.
Hace 4 días · A system of inequalities is a set of two or more inequalities in one or more variables. Systems of inequalities are used when a problem requires a range of solutions, and there is more than one constraint on those solutions.
Hace 5 días · Given integers A, B, C, and D denoting the length of sides of a Cyclic Quadrilateral, the task is to find the circumradius i.e., the radius of circumcircle of the given cyclic quadrilateral. Examples: Input: A = 3, B = 4, C = 5, D= 6. Output: 3.29. Input: A = 10, B = 30, C = 50, D = 20. Output: 27.78.
Hace 3 días · A wire of infinite length is kept along z-axis from the coordinate $z = - \infty $ to $z = + \infty $ and its linear charge density (λ) is $\dfrac{{10}}{9}nC/m$ . A linear charge density is defined as charge carried by the wire per unit length.
