yeah i was thinking of gradient descent (They are pretty similar though... sort of... not really.. =P i dunno..)
How do you do x^(1/2.5) // two point fifth root? (No such thing..?)
oh shit its hell simple... 2 / 1.5 [ = 1.5 ?] (as in 1.5 * 1.5 = 2 ? )
so a cuberoot would be 2 / (1.5 * 1.5) [ = 1.5 ?]...? and 2.5 is a pain? =)
