Polar equation to cartesian equation calculator

How do you convert polar equation to Cartesian equation?

Summary. To convert from Polar Coordinates (r,θ) to Cartesian Coordinates (x,y) : x = r × cos( θ ) y = r × sin( θ )

What is polar equation?

Polar Equations A polar equation is any equation that describes a relation between r r r and θ theta θ, where r r r represents the distance from the pole (origin) to a point on a curve, and θ theta θ represents the counterclockwise angle made by a point on a curve, the pole, and the positive x x x-axis.

What is Cartesian equation of a line?

The cartesian equation for a straight line is y = mx + c, where m represents the gradient of the line, and c is the point where the line crosses the y-axis. A vector equation for a line similarly needs 2 pieces of information: A point on the line. The direction of the line .

What is Cartesian equation of curve?

A cartesian equation for a curve is an equation in terms of x and y only. Definition. Parametric equations for a curve give both x and y as functions of a third variable (usually t).

What is a Cartesian equation of a circle?

Cartesian coordinate system with a circle of radius 2 centered at the origin marked in red. The equation of a circle is (x − a)2 + (y − b)2 = r2 where a and b are the coordinates of the center (a, b) and r is the radius.

What is polar and Cartesian coordinates?

Polar Coordinates. Main Concept. The Cartesian coordinate system is a two-dimensional coordinate system using a rectilinear grid: • The x and y coordinates of a point measure the respective distances from the point to a pair of perpendicular lines in the plane called the coordinate axes, which meet at the origin.

Equation of vertical line

How do you write an equation for a vertical and horizontal line? Horizontal lines go left and right and are in the form of y = b where b represents the y intercept. Vertical lines go up and down and are in the form of x = a where a represents the shared x coordinate […]

Bernoulli’s equation example

What does Bernoulli’s equation State? Bernoulli’s principle states the following, Bernoulli’s principle: Within a horizontal flow of fluid, points of higher fluid speed will have less pressure than points of slower fluid speed. Why is Bernoulli’s equation used? The Bernoulli equation is an important expression relating pressure, height and velocity of a fluid at one […]
