Coordinate Transformation
How do you change from a radial coordinate system to Cartesian coordinate system?!
Cartesian Coordinate System
- $x$
- $y$
Radial Coordinate System
- $r$
- $\theta$
- °
Cartesian Update- $x$
x = <r-dynamic :value="x" :change="{x: value}"></r-dynamic>Cartesian Update - $y$
y = <r-dynamic :value="y" :change="{y: value}"></r-dynamic>Radius Update - $r$
r &= \sqrt{x^2 + y^2} = \\ x &= r \cos(\operatorname{atan2}(y, x)) = \\ y &= r \sin(\operatorname{atan2}(y, x)) = <r-dynamic :value="Math.sqrt(x*x + y*y)" :change="{ x: value * Math.cos(Math.atan2(y, x)), y: value * Math.sin(Math.atan2(y, x)) }"></r-dynamic>Theta Update - $\theta$
\theta &= \operatorname{atan2}(y, x) = \\ x &= \sqrt{x^2 + y^2} \cos( \theta ) = \\ y &= \sqrt{x^2 + y^2} \sin( \theta ) = <r-dynamic :value="Math.atan2(y, x)" :change="{ x: Math.sqrt(x*x + y*y) * Math.cos(value), y: Math.sqrt(x*x + y*y) * Math.sin(value) }"></r-dynamic>Made with love by
