A logistic function has the following formula; For the left most equation to be 'easy,' a common number in this series is 1, yes? that means it could be very likely that [x] = 1, and there would be no problem. in fact, if it balances, where there are no negative numbers, this would be very likely. Then, the right most equation; this should be [3f 3x] * [1f * 1x -1] = [4f 4x] - 1. seeing as how this is a study of curves, the value is one degree, as that would be such a big curve, yet compressed by many times to produce 'a sized down curve.' this means that the curve can be calculated as one, then multiplied by the other values, and then compressed or expanded - i am not sure - to fit with the rest of the values. this is for a cylinder though. For example, if the curve is really thirty degrees, and you have estimated this, then you have a guideline as to how to apply your 'answers.' this would be where the [4f 4x] -1 equals something close to , so, you would divide thirty degrees by seven, bringing the values down to be fitted into the one degree curve you worked off of. so, if [1f] = 4 then the answer would be, for [4f], [16f.] if the [x] was 5, then the answer there would be 20, making for a equation of 16 * 20, coming to 36. if you take seven, as we found on the most basic of equations, to multiply by 5 you would get 35, yes? with that minus one, 36 becomes 35! this means that you may reduce all your values to one for this, and, then, just scale to ratio it into working order.
