How do you find the general solution of the differential equation dy/dx = y * e^(2x)?

Finding the General Solution of the Differential Equation

To find the general solution of the differential equation given by

dy/dx = y * e^(2x)

we can use the method of separation of variables. Here’s a step-by-step approach:

Step 1: Separate the Variables

We start by rewriting the equation to isolate y and x on opposite sides:

    dy/y = e^(2x) dx
    

Step 2: Integrate Both Sides

Next, we integrate both sides. The left side is the integral of 1/y and the right side is the integral of e^(2x):

    ∫(1/y) dy = ∫e^(2x) dx
    

This results in:

    ln|y| = (1/2)e^(2x) + C
    

where C is the constant of integration.

Step 3: Solve for y

To solve for y, we exponentiate both sides:

    |y| = e^((1/2)e^(2x) + C)
    

This can be simplified to:

    y = ±e^C * e^(1/2)e^(2x).
    

Step 4: Simplifying the Solution

Letting K = ±e^C, we can express the solution as:

    y = K * e^(x^2)
    

Thus, the general solution of the differential equation dy/dx = y * e^(2x) is:

    y = K * e^(x^2)
    

where K is an arbitrary constant.
