 Mar22 awarded Yearling Mar6 accepted Representing rotations using quaternions Mar4 comment Representing rotations using quaternions @RespawnedFluff These articles are too technical for me to understand, but as far as I could, with a 3 dimensional representation of rotations in a 3D space, there could be some cases where a rotation can be denoted by two different numbers. Is that so? For the constructor, it may be a conversion from Euler angles but the documentation doesn't refer to Euler angles at any point. Mar4 comment Representing rotations using quaternions @AvZ Haha, it's kind of a broad subject but as I wrote in the question, I'm using a game engine called Unity and C# language. The rotation animation I asked about is explained in this tutorial around 19:00. Mar4 comment Representing rotations using quaternions @AvZ Not at all, I was just trying to create some animations in a game.

Is that right? Dec29 asked Euclidian division of polynomials Oct30 comment Find all real solutions of $\,(x^2+2)^3 = x^2 \cdot (x^4-2)^5$ I'd like to say to expand the expression $(x^2+2)^3-x^2(x^4-2)^5$, factoring with the highest exponent of $x$ ($x^{22}$) and reducing to a unique fraction the appearing expression but it's still a huge job...
