Full solution

Q. What is the particular solution to the differential equation dydx\frac{dy}{dx}=4x2e2y\frac{4}{x^{2}e^{2y}} with the initial condition y(1)=0y(1)=0 ?
  1. Separate variables: Separate the variables in the differential equation.\newlineWe want to get all the yy terms on one side and all the xx terms on the other side. We can do this by multiplying both sides by e2ye^{2y} and dxdx, and dividing both sides by x2x^2.\newlinee2ydy=(4x2)dxe^{2y} dy = \left(\frac{4}{x^2}\right) dx
  2. Integrate both sides: Integrate both sides of the equation.\newlineWe need to integrate e2ye^{2y} with respect to yy and 4x2\frac{4}{x^2} with respect to xx.\newlinee2ydy=(4x2)dx\int e^{2y} dy = \int \left(\frac{4}{x^2}\right) dx
  3. Perform integration: Perform the integration.\newlineThe integral of e2ye^{2y} with respect to yy is (12)e2y(\frac{1}{2})e^{2y}, and the integral of 4x2\frac{4}{x^2} with respect to xx is 4x-\frac{4}{x}.\newline(12)e2y=4x+C(\frac{1}{2})e^{2y} = -\frac{4}{x} + C, where CC is the constant of integration.
  4. Solve for constant: Solve for the constant of integration using the initial condition.\newlineWe are given that y(1)=0y(1) = 0. Plugging these values into our integrated equation gives us:\newline(1/2)e(20)=4/1+C(1/2)e^{(2*0)} = -4/1 + C\newline(1/2)1=4+C(1/2)*1 = -4 + C\newlineC=4+1/2C = 4 + 1/2\newlineC=4.5C = 4.5
  5. Write particular solution: Write the particular solution with the constant.\newlineNow that we have the value of CC, we can write the particular solution:\newline12e2y=4x+4.5\frac{1}{2}e^{2y} = -\frac{4}{x} + 4.5
  6. Check with initial condition: Check the solution with the initial condition.\newlinePlugging x=1x = 1 and y=0y = 0 into the particular solution to see if both sides are equal:\newline(1/2)e(20)=4/1+4.5(1/2)e^{(2\cdot 0)} = -4/1 + 4.5\newline1/2=4+4.51/2 = -4 + 4.5\newline1/2=0.51/2 = 0.5\newlineBoth sides are equal, so the initial condition is satisfied.
