Q. Can this differential equation be solved using separation of variables?dxdy=2y−xyChoose 1 answer:(A) Yes(B) No
Check for Separation: To determine if the differential equation can be solved using separation of variables, we need to see if we can express the equation in the form of (dxdy)=g(x)dx, where g(x) is a function of x only.
Rewrite the Equation: First, we rewrite the differential equation as dxdy=y(2−x).
Separate Variables: Now, we attempt to separate the variables by dividing both sides of the equation by y and multiplying both sides by dx to get (1/y)dy=(2−x)dx.
Integrate Both Sides: We have successfully separated the variables, with y on one side and x on the other. This means we can integrate both sides with respect to their respective variables.
Final Solution: The integral of (1/y)dy is ln∣y∣, and the integral of (2−x)dx is 2x−(x2)/2+C, where C is the constant of integration.
Final Solution: The integral of (1/y)dy is ln∣y∣, and the integral of (2−x)dx is 2x−(x2)/2+C, where C is the constant of integration.Thus, the solution to the differential equation after integrating both sides is ln∣y∣=2x−(x2)/2+C.
