WebJun 29, 2024 · Is it possible to add the derivative of the sigmoid function to the graph using a red dotted line, including a legend in the topright corner for both lines without leaving the tikz environment? Sigmoid function: σ = 1/(1+exp(-x)) Derivative: σ(x)(1−σ(x) WebTo create a log axis: Double-click on the axis to open the Format Axes dialog. In the Scale section, set the axis to Log10 or Log 2 or Ln (natural logarithm). This graph shows log10 spaced minor ticks. The minor ticks between the major ticks at 10 and 100 show the position of 20, 30, 40, 50, 60, 70, 80 and 90.
