BERNOULLI EQUATION:
A Bernoulli equation is a first order equation
𝑦′(𝑥) + 𝑃(𝑥)𝑦 = 𝑅(𝑥)𝑦 𝛼
In which 𝛼 is a real number.
A Bernoulli equation is separable if 𝛼 = 0 and linear if 𝛼 = 1. About 1696, Leibniz
showed that a Bernoulli equation with 𝛼 ≠ 1 transforms to a linear equation under
the change of variables
𝑣 = 𝑦1−𝛼
