## What is a phasor in math?

PHASORS AND COMPLEX. NUMBER MATHEMATICS. Phasors are time-varying vectors that exist in the complex plane. The complex plane consists of a horizontal axis (the real axis) and a vertical axis (the imaginary axis). A graphical representation of the complex plane is called an Argand diagram.

## What is J3?

The Operations (J3) directorate is the Continental Staff System branch of the U.S. DOD Joint Staff responsible for military operations.

What is J in math?

j is an imaginary number such that j2 = −1. Even though j is not real, using it we can formally write down the square roots of any negative number as shown in the following example. Example Write down expressions for the square roots of a) 9, b) −9.

Can you multiply phasors?

To multiply two phasors, we should first convert them to polar form to make things simpler. The product in polar form is simply the product of their magnitudes, and the phase is the sum of their phases. Keep in mind that in polar form, phasors are exponential quantities with a magnitude (M), and an argument (φ).

### What is J9 in the military?

In high-level tri-service, or joint headquarters (JHQ), the department is termed “J9”.

### Who is the J2?

J-2 serves as the Intelligence Community manager for Support to Military operations, and is the Director of the Joint Warfighting Capabilities Assessments for Intelligence, Surveillance, and Reconnaissance under the Joint Requirements Oversight Council. J2 Leadership.

How do you explain phasor diagram?

Phasor Diagram A phasor is a scaled line whose length represents an AC quantity that has both magnitude (peak amplitude) and direction (phase) which is frozen at some point in time. A phasor diagram is used to show the phase relationships between two or more sine waves having the same frequency.

Why do we use phasors?

Phasors are a useful visualization of what’s going on in an AC circuit (and in fact for many situations involving sinusoidal waves).
