Figure 1 shows a graph of V against I for a filament lamp. Calculate the maximum resistance of the lamp over the range shown by the graph,

now i have a somewhat vague attempt and its to measure the tangent of the line (i can't upload the graph sorry)

how do i take a tangent of a curved line accurately and then calculate the maximum resistance

thank you for your help
