Need help rotating a parabola on cartesian coordinate system

Click For Summary

Discussion Overview

The discussion revolves around the challenge of rotating the parabola defined by the equation y=x² on a Cartesian coordinate system by 90 degrees about the origin. Participants explore methods to achieve this rotation without employing piecewise or inverse functions, focusing on translations and deformations.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested, Mathematical reasoning

Main Points Raised

  • One participant seeks to rotate the parabola y=x² by 90 degrees about the origin using translations and deformations.
  • Another participant suggests considering a rotation matrix and representing the function parametrically as a potential method for transformation.
  • There is a mention of a "Math Processing Error" affecting the visibility of equations, which some participants note as problematic.
  • One participant expresses a lack of familiarity with linear algebra and inquires about the possibility of a non-calculus solution.

Areas of Agreement / Disagreement

Participants have not reached a consensus on the method to rotate the parabola, and multiple approaches are being discussed without resolution.

Contextual Notes

Some participants express uncertainty regarding their familiarity with linear algebra, which may affect their contributions to the discussion. The mention of a "Math Processing Error" indicates potential limitations in communication of mathematical ideas.

Who May Find This Useful

This discussion may be of interest to individuals exploring transformations in coordinate systems, particularly those with a focus on mathematical reasoning and linear algebra applications.

Okay I need to rotate a parabola on a cartesian coordinate system, y=x^2 by 90 degrees about the origin (either direction) without using piecewise, or inverse functions. Basically I am trying to use translations and deformations to accomplish this.

Anyone thoughts?

Looks fine to me.

How much experience do you have with linear algebra? Consider a rotation matrix; can you think of a way to it use to transform your parabola? Maybe try representing your function parametrically.

It just started working, I can see it now.

Not familiar with this, is there a non calculus solution?
