What is the general solution of the differential equation?
A solution of a differential equation is an expression for the dependent variable in terms of the independent one(s) which satisfies the relation. The general solution includes all possible solutions and typically includes arbitrary constants (in the case of an ODE) or arbitrary functions (in the case of a PDE.)

What is the general solution?
Definition of general solution 1 : a solution of an ordinary differential equation of order n that involves exactly n essential arbitrary constants. — called also complete solution, general integral. 2 : a solution of a partial differential equation that involves arbitrary functions.
What do you mean by general solution and particular solution of a differential equation?
If the number of arbitrary constants in the solution is equal to the order of the differential equation, the solution is called as the general solution. If the arbitrary constants in the general solution are given particular values, the solution is called a particular solution (of the differential equation).

How do you use DX dy?
dy/dx means you differentiate y with respect to x, or differentiate implicitly and then divide by dx; So to calculate dx/dy, differentiate x with respect to y, or differentiate implicitly and then divide by dy. Or if you’ve already calculated dy/dx, then simply take it’s reciprocal as dx/dy.
What is the general solution of linear differential equation py Q?
A general first-order differential equation is given by the expression: dy/dx + Py = Q where y is a function and dy/dx is a derivative. The solution of the linear differential equation produces the value of variable y.
What is general solution with example?
The general solution geometrically represents an n-parameter family of curves. For example, the general solution of the differential equation \frac{dy}{dx} = 3x^2, which turns out to be y = x^3 + c where c is an arbitrary constant, denotes a one-parameter family of curves as shown in the figure below.
