Need Help: Cartesian to Polar Coordinates

Click For Summary
SUMMARY

The discussion focuses on converting Cartesian coordinates to polar coordinates, specifically for the points (2, -4) and (-3, 3). The process involves calculating the radius and angle using trigonometric functions. Key resources provided include MathWorld's guide on polar coordinates and a visual calculus archive that offers step-by-step explanations. This conversion is essential for understanding spatial relationships in physics.

PREREQUISITES
  • Understanding of Cartesian coordinates
  • Basic trigonometry, including sine and cosine functions
  • Familiarity with the concept of angles in radians and degrees
  • Knowledge of distance calculation between two points
NEXT STEPS
  • Learn how to calculate the radius in polar coordinates using the formula r = √(x² + y²)
  • Study how to determine the angle θ using the formula θ = arctan(y/x)
  • Explore the conversion formulas between Cartesian and polar coordinates
  • Review applications of polar coordinates in physics and engineering contexts
USEFUL FOR

Students returning to physics, educators teaching coordinate systems, and anyone needing to refresh their knowledge on converting between Cartesian and polar coordinates.

Just got back into physics after 4 years in social science and I have forgotten how to convert cartesian coordinates to polar coordinates. The textbook I have makes no metion of it. probably bc I am expected to know this, but I can't remember. I remember how to calculate the distace between two points, but that's it. The two points I have are (2,-4) and (-3,3)

Thanks
