How to Solve Ecuaciones 23 with Yu Takeuchi’s Method
To solve this equation using the method of variables separables, we need to rearrange it so that all the terms involving y are on one side and all the terms involving x are on the other side. We can do this by multiplying both sides by xy and then adding x^2 to both sides. This gives us:
Now we can divide both sides by (y2) and separate the variables. This gives us:
The next step is to integrate both sides with respect to their respective variables. This will give us two functions of one variable each, plus a constant of integration. We can use partial fractions to simplify the integrals. The left-hand side becomes:
The right-hand side becomes:
where C is an arbitrary constant. This is the general solution of the differential equation. To find a particular solution, we need to know an initial condition, that is, a pair of values (x0,y0) that satisfy the equation. For example, if we are given that y(1)=1, then we can plug in x=1 and y=1 into the general solution and solve for C. This gives us:
Therefore, the particular solution that satisfies y(1)=1 is:
This is the final answer. We can check that it satisfies the original differential equation by differentiating it with respect to x and simplifying. We can also plot the solution curve using a graphing calculator or software.
