(For the sake of intuition, 1/√0=0)

    I’m not sure I understand your mnemonic. It looks like you’ve got 1/sqrt(3) as one of your exact value for sine and cosine… but that surely isn’t right.

    My trick for this was:

    0  30  45  60  90 deg
---------------------------
0  1   2   3   4

    Sine function of the top equals half the square root of the bottom number. Cosine is just in reverse order.
