    Undergrad Trigonometry puzzle

    Ok, not originally mine: A message was encrypted as: $$\frac{sinq}{cosq}\times{\sqrt(\frac{-1}{64})}$$ What is the meaning of it? @berkeman , thanks for the edit.

    Undergrad Tensors, tensor products

    My take is that the Tensor product of Vector Spaces $$V, W$$ over the same field F, gives rise to a new Tensor Vector space , where every bilinear map on $$V \times W$$ into a base field(ring?) factors into a linear map from $$V \otimes W$$ into the same base ring/field.

    Undergrad Roulette system -- which optimization is better?

    There was some one who modeled the roulette programmatically, entered the initial conditions and produced an educated guess. Can't remember the details, but they broke even. It was in the ( non- fiction) book " The Eudemonic Pie" The modeling device was kept hidden under a hat.

    Studying What math and physics do I need to learn before studying quantum mechanics?

    I'd say a good book on Advanced Calculus , meant in a broader sense, i.e., including basic Linear Algebra ( Derivative as a matrix, locally- linear map), should give you all the Math you need to start . I remember Borden's book , but there are a few free such books online.
