Polar equation to rectangular

How do you convert rectangular form to polar form?

To convert from polar to rectangular, find the real component by multiplying the polar magnitude by the cosine of the angle, and the imaginary component by multiplying the polar magnitude by the sine of the angle.

What is polar and rectangular form?

In Rectangular Form a complex number is represented by a point in space on the complex plane. In Polar Form a complex number is represented by a line whose length is the amplitude and by the phase angle.

What is rectangular equation?

A rectangular equation, or an equation in rectangular form is an equation composed of variables like x and y which can be graphed on a regular Cartesian plane. For example y=4x+3 is a rectangular equation.

Are Cartesian and rectangular coordinates the same?

The Cartesian coordinates (also called rectangular coordinates) of a point are a pair of numbers (in two-dimensions) or a triplet of numbers (in three-dimensions) that specified signed distances from the coordinate axis.

What is polar form?

The polar form of a complex number is another way to represent a complex number. The form z=a+bi is called the rectangular coordinate form of a complex number. The horizontal axis is the real axis and the vertical axis is the imaginary axis.

What is the difference between a rectangular equation and a parametric equation?

The difference between parametric equations and rectangular equations is that where a rectangular equation only requires one equation, a parametric equation is made up of one definition equation for each variable.

What is Cartesian equation?

: an equation of a curve or surface in which the variables are the Cartesian coordinates of a point on the curve or surface.

What is T in parametric equations?

The variable t is called a parameter and the relations between x, y and t are called parametric equations. The set D is called the domain of f and g and it is the set of values t takes. Conversely, given a pair of parametric equations with parameter t, the set of points (f(t), g(t)) form a curve in the plane.

What is the difference between polar and Cartesian coordinates?

This leads to an important difference between Cartesian coordinates and polar coordinates. In Cartesian coordinates there is exactly one set of coordinates for any given point. With polar coordinates this isn’t true. In polar coordinates there is literally an infinite number of coordinates for a given point.

Navier-stokes equation

Is the Navier Stokes equation solved? In particular, solutions of the Navier–Stokes equations often include turbulence, which remains one of the greatest unsolved problems in physics, despite its immense importance in science and engineering. Even more basic properties of the solutions to Navier–Stokes have never been proven. Who Solved Navier Stokes? Russian mathematician Grigori Perelman […]

Equation for moment of inertia

How is moment of inertia calculated? Basically, for any rotating object, the moment of inertia can be calculated by taking the distance of each particle from the axis of rotation (r in the equation), squaring that value (that’s the r2 term), and multiplying it times the mass of that particle. What is moment of inertia […]
