# How can I automate code to plot a line between two points?

Currently trying to create an automated function that can find a line between two points. Tried testing this function (by plotting) but when I plot the function I get a ‘v-shaped’ line. What changes can I make to complete this function? Thanks. import matplotlib.pyplot as plt from math import e x = [0, 9] y… Read More How can I automate code to plot a line between two points?

# Having trouble inverting a simple math equation using logarithms in Python

After trying to reverse a very simple math formula for the past day, I’ve given up after bumping my head against scipy.special.lambertw — which might not even be the correct place to be looking. I have the following equation: import numpy # The following == 70.03 np.sqrt(np.log(742) * 742) I’m trying to invert that equation… Read More Having trouble inverting a simple math equation using logarithms in Python
