Example Solution
-
The provided equation is a first-order differential equation.
-
It involves the derivative of a function ‘y’‘y’‘y’ with respect to ‘x’‘x’‘x’, denoted by dy/dx{dy/dx}dy/dx.
-
The equation also includes trigonometric functions (tan) and algebraic terms (‘x’‘x’‘x’).
-
Solving this equation requires using techniques like substitution.
-
We begin by substituting u=y−x,du/dx=dy/dx−1u=y-x, \quad {du/dx}={dy/dx}-1u=y−x,du/dx=dy/dx−1
- Substitute into the original equation: du/dx−1=xtan(u).du/dx-1=x\tan(u).du/dx−1=xtan(u).
- Separate variables to solve the differential equation: 1xtan(u)+1du=dx\frac{1}{x\tan(u)+1}du=dx x tan(u)+11du=dx.
-
The solution requires non-elementary function integration.The resulting differential equation requires solving techniques involving substitution and variable separation.on: ∫1xtan(u)+1du=∫dx\int \frac{1}{x\tan(u)+1}du=\int dx∫xtan(u)+11du=∫dx gives the solution of y(x) in an implicit form.
