Is 3i an irrational number?
No. It is an imaginary (or complex) number.
Is every real number a complex number?
A complex number is a number of the form a + bi, where a and b are real numbers and i is the principal square root of -1. In the special case where b=0, a+0i=a. Hence every real number is also a complex number. And in the special case where a=0, we call those numbers pure imaginary numbers. Note that 0=0+0i, therefore 0 is both a real number and a pure imaginary number. Do not confuse the complex numbers with the pure imaginary numbers. Every real number is a complex number and every pure imaginary number is a complex number also.
What is a complex decimal?
A complex decimal is a combination of a real number and an imaginary number. A few examples include 123 + i = 123i.

A complex number is a number of the form a plus bi where?
"a + bi" is a common way to write a complex number. Here, "a" and "b" are real numbers.Another common way to write a complex number is in polar coordinates - basically specifying the distance from zero, and an angle.
How can we show that the position operator is Hermitian?
To show that the position operator is Hermitian, we need to demonstrate that its adjoint is equal to itself. In mathematical terms, this means proving that the integral of the complex conjugate of the wave function multiplied by the position operator is equal to the integral of the wave function multiplied by the adjoint of the position operator. This property is essential in quantum mechanics as it ensures that the operator corresponds to a physical observable.
Can you make momentum operator non self adjoint?
No, the momentum operator in quantum mechanics must be self-adjoint in order to ensure that it generates unitary time evolution and that the associated probability distribution is conserved. Making the momentum operator not self-adjoint would lead to inconsistencies with the fundamental principles of quantum mechanics.
How can one determine if an operator is Hermitian?
To determine if an operator is Hermitian, one must check if the operator is equal to its own conjugate transpose. This means that the operator's adjoint is equal to the operator itself. If this condition is met, then the operator is Hermitian.
What is a Hermitian operator?
A Hermitian operator is a linear operator that is equal to its own adjoint. In other words, the adjoint of a Hermitian operator is the same as the operator itself. Hermitian operators play a key role in quantum mechanics as they correspond to observable physical quantities.
Is momentum hamiltonian operator is hermitian operator?
The hamiltonian operator is the observable corresponding to the total energy of the system. As with all observables it is given by a hermitian or self adjoint operator. This is true whether the hamiltonian is limited to momentum or contains potential.

What is an adjoint matrix?
The classical adjoint of a square matrix A the transpose of the matrix who (i, j) entry is the a i j cofactor.
How can you create a new operator through operator overloading?
You cannot create a new operator through operator overloading. You can only redefine an existing operator, with certain limitations. As an example, for a class of complex numbers, having a real and an imaginary part, you might want an addition operator. This is the skeleton of code to do that. I only show the operator, not any constructors or other operators or methods, etc.class complex {private:double real, imaginary;public:complex operator+ (complex operand) {complex temp;temp.real = this.real + operand.real;temp.imaginary = this.imaginary + operand.imaginary;return temp;}};The above answer is for C++. Since this question is also categorized in Java Programming it's important to note that operator overloading is not currently possible in Java.
What is the operator number in the UK?
The main number for reaching a telephone operator in the UK is 100.
What is the significance of the adjoint spinor in the context of quantum field theory?
The adjoint spinor in quantum field theory is important because it represents the conjugate of a spinor, which allows for the calculation of complex quantities like probabilities and interactions in particle physics. It helps in understanding the symmetries and transformations of particles and fields, making it a crucial concept in theoretical physics.
Write a program to write the sum of two complex number using friend function and overloading constractor?

What is the function of operator 'j' in alternating current?
The operator 'j' represents the imaginary unit in alternating current circuits. It is used to denote the phase difference or angular displacement between voltage and current waveforms in complex impedance calculations. The use of 'j' helps in simplifying mathematical calculations in AC circuits by treating the impedance as a complex number.
