Find Integrating Factor: We are given a first-order linear non-homogeneous differential equation of the form dtdy+P(t)y=Q(t), where P(t)=5 and Q(t)=x(t). To solve this, we will first find the integrating factor, which is e(∫P(t)dt). In this case, the integrating factor is e(∫5dt)=e5t.
Multiply by Integrating Factor: Now we multiply the entire differential equation by the integrating factor e5t to get e5t⋅dtdy+5e5t⋅y(t)=e5t⋅x(t).
Rewrite Differential Equation: Notice that the left side of the equation is the derivative of the product of the integrating factor and y(t), which is dtd(e5t⋅y(t)). So we can rewrite the equation as dtd(e5t⋅y(t))=e5t⋅x(t).
Integrate Both Sides: We will now integrate both sides of the equation with respect to t. The left side becomes e5t⋅y(t), and the right side requires integrating e5t⋅x(t) with respect to t, which we will denote as ∫e5t⋅x(t)dt.
Solve for y(t): After integrating, we have e5t⋅y(t)=∫e5t⋅x(t)dt+C, where C is the constant of integration.
Solve for y(t): After integrating, we have e5t⋅y(t)=∫e5t⋅x(t)dt+C, where C is the constant of integration.To solve for y(t), we divide both sides by e5t, yielding y(t)=(e5t1)⋅(∫e5t⋅x(t)dt+C).
