this post has a similar derivation, but it is sloppier: http://www.clayford.net/statistics/deriving-the-exponential-distribution/ (e.g. it doesn't do <math>f(w) = \lambda e^{-\lambda w}</math>) | this post has a similar derivation, but it is sloppier: http://www.clayford.net/statistics/deriving-the-exponential-distribution/ (e.g. it doesn't do <math>f(w) = \lambda e^{-\lambda w}</math>) | ||
this one goes from the geometric distribution, and i think it's also ok https://math.stackexchange.com/questions/913871/deriving-exponential-distribution-from-geometric?rq=1 (the derivation of the poisson distribution also does a similar thing) | |||

this is the only derivation that makes any sense to me (assuming you already understand the poisson distribution): https://neurophysics.ucsd.edu/courses/physics_171/exponential.pdf
