Full solution

Q. Solve the differential equation.\newlinedydx=e2x2y\frac{dy}{dx}=e^{2x-2y}
  1. Rearrange equation for separation: We are given the differential equation (dydx)=e2x2y(\frac{dy}{dx}) = e^{2x-2y}. To solve this, we will use the method of separation of variables, which involves rearranging the equation so that all terms involving yy are on one side and all terms involving xx are on the other side.
  2. Integrate with respect to variables: First, we rewrite the equation to separate the variables xx and yy:dydx=e2x2y\frac{dy}{dx} = e^{2x-2y}We can write this as e2ydy=e2xdxe^{2y} dy = e^{2x} dx.
  3. Apply constant of integration: Next, we integrate both sides of the equation with respect to their respective variables. This means we will integrate e2ye^{2y} with respect to yy and e2xe^{2x} with respect to xx.
  4. Eliminate fraction: The integral of e2ydye^{2y} \, dy is (12)e2y(\frac{1}{2})e^{2y}, and the integral of e2xdxe^{2x} \, dx is (12)e2x(\frac{1}{2})e^{2x}. So we have:\newline(12)e2y=(12)e2x+C(\frac{1}{2})e^{2y} = (\frac{1}{2})e^{2x} + C, where CC is the constant of integration.
  5. Take natural logarithm: We multiply both sides of the equation by 22 to get rid of the fraction:\newlinee2y=e2x+2Ce^{2y} = e^{2x} + 2C.
  6. Simplify using logarithm property: Now, we take the natural logarithm of both sides to solve for yy: ln(e2y)=ln(e2x+2C)\ln(e^{2y}) = \ln(e^{2x} + 2C).
  7. Solve for y: Using the property of logarithms that ln(eu)=u\ln(e^u) = u, we simplify the left side to get: 2y=ln(e2x+2C)2y = \ln(e^{2x} + 2C).
  8. Solve for y: Using the property of logarithms that ln(eu)=u\ln(e^u) = u, we simplify the left side to get:2y=ln(e2x+2C)2y = \ln(e^{2x} + 2C).Finally, we divide both sides by 22 to solve for y:y=(12)ln(e2x+2C)y = (\frac{1}{2})\ln(e^{2x} + 2C).
