Rearrange equation for separation: We are given the differential equation (dxdy)=e2x−2y. To solve this, we will use the method of separation of variables, which involves rearranging the equation so that all terms involving y are on one side and all terms involving x are on the other side.
Integrate with respect to variables: First, we rewrite the equation to separate the variables x and y:dxdy=e2x−2yWe can write this as e2ydy=e2xdx.
Apply constant of integration: Next, we integrate both sides of the equation with respect to their respective variables. This means we will integrate e2y with respect to y and e2x with respect to x.
Eliminate fraction: The integral of e2ydy is (21)e2y, and the integral of e2xdx is (21)e2x. So we have:(21)e2y=(21)e2x+C, where C is the constant of integration.
Take natural logarithm: We multiply both sides of the equation by 2 to get rid of the fraction:e2y=e2x+2C.
Simplify using logarithm property: Now, we take the natural logarithm of both sides to solve for y: ln(e2y)=ln(e2x+2C).
Solve for y: Using the property of logarithms that ln(eu)=u, we simplify the left side to get: 2y=ln(e2x+2C).
Solve for y: Using the property of logarithms that ln(eu)=u, we simplify the left side to get:2y=ln(e2x+2C).Finally, we divide both sides by 2 to solve for y:y=(21)ln(e2x+2C).
