Problem 21E

PROBLEM 21E

Each DE in Problems 15–22 is a Bernoulli equation.

In Problems 21 and 22 solve the given initial-value problem. Step-by-Step Solution:

Solution:Step 1</p>

In this problem we need to solve the given initial value problem.

Step 2</p> First we arranging the differential equation to change it to the standard form of bernoulli's equation i.e. by dividing both sides by , we get Dividing both sides by , we get  To solve this we make the substitution .

Differentiating with respect to y, we get From above equation we get .

We can write as follows   Step 3</p>

Substituting and in the differential equation , we get  Multiplying both sides by , we get The equation is not in the standard form of bernoulli’s equation. To calculate the integrating factor, we do as follows    Step 4 of 5

Step 5 of 5
