To find the general solution of the differential equation dy/dx = 2y e^(3x)
, we can begin by recognizing that this is a first-order linear ordinary differential equation.
The equation can be rearranged to separate the variables:
dy/y = 2 e^(3x) dx
Now, we can integrate both sides. The left side, dy/y
, integrates to ln|y|
, and the right side integrates as follows:
∫2 e^(3x) dx = (2/3)e^(3x) + C
Let’s put this all together:
ln|y| = (2/3)e^(3x) + C
To eliminate the natural logarithm, we exponentiate both sides:
|y| = e^((2/3)e^(3x) + C)
We can express the constant term e^C
as another constant K
(where K = e^C
, K > 0). This gives us:
y = Ke^((2/3)e^(3x})
Since K
can be positive or negative, we can drop the absolute value and simply write:
y = Ke^((2/3)e^(3x}
Thus, the general solution to the differential equation dy/dx = 2y e^(3x)
is:
y = Ke^((2/3)e^(3x)
where K
is any real constant.
