 TOPICS # Bernoulli Differential Equation (1)

Let for . Then (2)

Rewriting (1) gives   (3)   (4)

Plugging (4) into (3), (5)

Now, this is a linear first-order ordinary differential equation of the form (6)

where and . It can therefore be solved analytically using an integrating factor   (7)   (8)

where is a constant of integration. If , then equation (◇) becomes (9) (10) (11)

The general solution is then, with and constants, (12)
