    f(x) = f(x+2) = f(x+2L) by definition, so L=1

    Was sent to this video by a Pikuma course on 3D graphics. This video did help, but I felt like there were several places where a bunch of steps were skipped, and it took me a bit to figure out the missing pieces. Also, the low framerate made things hard to follow at times. Not incredibly intuitive overall. Also, the thing about assuming that lambda is 1 at the end to "get rid of it" was a bit confusing. I suppose the point is that lambda can be whatever we want, and when we assume it's the scalar 1 (it is a scalar and not a vector, right?), then it makes the math easy. I suppose I'm on board with that (assuming I'm understanding it correctly), but confusing.

    Make videos about constructible numbers and other mathematical objects also, like, the Euclidean geometry is always awesome, but go tangent, parallel & orthogonal in all directions, including theory of Liouville Hadamard Duhamel Wronskian general Solvability theory and expressible/Algebraic /Galois Theory & the Likes I would love to see a proper series in the direction one day Overall - learned a great deal from you my friend

    at 8:19, you use two different f's, tan(πx/4) and ax+b, in the same equation, is this correct?

  • @DrChrisTisdell

    f is piecewise defined, so you would expect different definitions depending on the domain.

    Nicely done. However, please finish the job. You found the angle that is 1/3 that of the original angle, but for completeness you should go ahead and apply that to finish trisecting the original arc.

    you can square both eurros and sum the squares then take square root of that square root of (1^2+2^2) will equal to (square root of 5 )% which is more accurate
