Math Problem Statement

𝑦′=𝑦

Solution

The given differential equation is:

yβ€²=yy' = y

This is a first-order linear differential equation, and we can solve it using separation of variables or by recognizing it as a standard equation with the solution y=Cexy = Ce^x, where CC is a constant.

Steps for solving:

  1. Rewrite the equation: dydx=y\frac{dy}{dx} = y

  2. Separate variables: 1y dy=dx\frac{1}{y} \, dy = dx

  3. Integrate both sides: ∫1y dy=∫dx\int \frac{1}{y} \, dy = \int dx The integral gives: ln⁑∣y∣=x+C1\ln|y| = x + C_1 where C1C_1 is a constant of integration.

  4. Solve for yy: Exponentiate both sides to eliminate the logarithm: ∣y∣=ex+C1=exβ‹…eC1|y| = e^{x + C_1} = e^{x} \cdot e^{C_1} Let C=eC1C = e^{C_1}, so: y=Cexy = Ce^x where CC is a constant.

Thus, the general solution to the differential equation yβ€²=yy' = y is:

y=Cexy = Ce^x
