The Roots Are Imaginary Because of the

Imaginary numbers are the numbers when squared it gives the negative result. The Standard Form of a Quadratic Equation looks like this.

It demonstrates the nature of the roots of any quadratic equation with rational coefficients a b and c A quadratic equation can simply indicate the real roots or the number of x-intercepts.

. Annals of Iowa - Iowa Research Online University of Iowa. Because the transfer function completely represents a system differential equation its poles and zeros effectively define the system response. Some authors use the name square root or the notation A 12 only for the specific case when A is positive semidefinite to denote the unique matrix B that is positive semidefinite and such that.

In particular the system poles directly define the components in the homogeneous response. In other words imaginary numbers are defined as the square root of the negative numbers where it does not have a definite value. In mathematics the square root of a matrix extends the notion of square root from numbers to matricesA matrix B is said to be a square root of A if the matrix product BB is equal to A.

A b and c are known valuesa cant be 0. Here are some examples. It is mostly written in the form of real numbers multiplied by the imaginary unit called i.

X is the variable or unknown we dont know it yet. The unforced response of a linear SISO system to a set of initial conditions is yht n i1 Cie λit 9. This formula is used to determine if the quadratic equations roots are real or imaginary.
