I am asked to solve the Homogeneous Linear DE: dy/dx - 3y = 0
I am trying to solve this by using an integrating factor by using the following procedure:
"int" in the equation above is "integral"
I am trying to solve this by using an integrating factor by using the following procedure:
d/dx[e^int(P(x) dx) * y] = e^int(P(x) dx) * f(x)
During the step-by-step solution of the DE the text makes the statement:e^(-3x) * dy/dx - 3e^(-3x) * y = 0 is the same as d/dx[e^(-3x) * y] = 0
My question is why are these two equations the same?"int" in the equation above is "integral"
