Derivative of logistic curve
WebMar 15, 2024 · And the derivative looks like this normal-function-esque hump. But the derivative is the rate of change of x/t not expressed as a percentage change in x. So my question is what does the graph of the percentage increase in x of the logistic function, over time, look like, and what would this graph/curve be called conversationally? WebThe derivative of the outside function (the natural log function) is one over its argument, so he go 1/N. Then he had to multiply this by the derivative of the inside function (which is N (t) ) with respect to time, which is dN/dt. Using the chain rule you get (d/dt) ln N = …
