To Convert from Cartesian to Polar. When we know a point in Cartesian Coordinates (x,y) and we want it in Polar Coordinates (r, θ) we solve a right triangle with two known sides. Example: What is (12,5) in Polar Coordinates? Use Pythagoras Theorem to find the long side (the hypotenuse): r 2 = 12 2 + 5 2. r = √ (12 2 + 5 2) r = √ (144 + 25)
Dec 22, 2023 · The conversion involves two primary formulas: To calculate the radial distance (r): r = sqrt (x^2 + y^2) To calculate the polar angle (θ), considering the quadrant: θ = atan2 (y, x) In these formulas: r: Represents the radial distance from the origin (0, 0) to the point (x, y). x: Denotes the x-coordinate of the point.
Feb 21, 2024 · To convert Cartesian coordinates (x, y) to polar coordinates (r, θ), you can use the following formulas: Calculate the radial distance (r): r = √(x 2 + y 2 ) Calculate the polar angle (θ): θ = arctan(y / x)
5 days ago · The polar coordinates r (the radial coordinate) and theta (the angular coordinate, often called the polar angle) are defined in terms of Cartesian coordinates by x = rcostheta (1) y = rsintheta, (2) where r is the radial distance from the origin, and theta is the counterclockwise angle from the x-axis.
Convert the Cartesian coordinates (3, 4) (3,4) to polar coordinates (r, \theta), (r,θ), where \theta θ is in radians and approximated up to two digits below the decimal point. By the Pythagorean theorem, we have r = \sqrt {3^2 +4^2} = 5. r = 32 +42 = 5.
