• exponential growth
  • exponential decay
  • decay in both direction
  • smoother version of above (no sharp edge)
  • The constant changes the base of exponentiation (it tweaks how “thin” the curve is)
  • where (standard deviation) is just that constant with more significant meaning (width)
  • Normalize the area under curve to be (because it is a PDF):
  • Adds another constant to describe the mean
