Is there zero order derivative equation?
I donot know whether there is actually a zero-order derivative equation, where the equation is defined as having two sides with equality or inequality sign between them. If the question is about a zero-order derivative function, then the answer is yes, since the zero order derivative is the function itself. ------------------ However, as far as we can talk about the differential equation- there is no meaning of "Zero Degree" but as many times while using expansion of differential operator using binomial theorem or while using Leibnitz's rule of differentiation, we simply denote derivatives of zero degree for no differentiation, we can say, for understanding, tha the equations without derivatives eg. y =mx can be treated as Differential Equation of Zero Order.

Collocation method for second order differential equation?
The collocation method for solving second-order differential equations involves transforming the differential equation into a system of algebraic equations by selecting a set of discrete points (collocation points) within the domain. The solution is approximated using a linear combination of basis functions, typically polynomial, and the coefficients are determined by enforcing the differential equation at the chosen collocation points. This approach allows for greater flexibility in handling complex boundary conditions and non-linear problems. The resulting system is then solved using numerical techniques to obtain an approximate solution to the original differential equation.
Is Hermitian first order differential operator a multiplication operator?
A Hermitian first-order differential operator is not generally a multiplication operator. While a multiplication operator acts by multiplying a function by a scalar function, a first-order differential operator typically involves differentiation, which is a more complex operation. However, in specific contexts, such as in quantum mechanics or under certain conditions, a first-order differential operator could be expressed in a form that resembles a multiplication operator, but this is not the norm. Therefore, while they can be related, they are fundamentally different types of operators.
How do you explain the term 'exact differential equation'?
An exact differential equation is a type of first-order differential equation that can be expressed in the form ( M(x, y) , dx + N(x, y) , dy = 0 ), where ( M ) and ( N ) are continuously differentiable functions. An equation is considered exact if the partial derivative of ( M ) with respect to ( y ) equals the partial derivative of ( N ) with respect to ( x ), i.e., ( \frac{\partial M}{\partial y} = \frac{\partial N}{\partial x} ). This condition indicates that there exists a function ( \psi(x, y) ) such that ( d\psi = M , dx + N , dy ). Solving an exact differential equation involves finding this function ( \psi ).
What is the difference between a first order and a second order differential equation?
A first order differential equation involves only the first derivative of the unknown function, while a second order differential equation involves the second derivative as well.

What is the Order of a differential equation?
The order of a differential equation is a highest order of derivative in a differential equation. For example, let us assume a differential expression like this. d2y/dx2 + (dy/dx)3 + 8 = 0 In this differential equation, we are seeing highest derivative (d2y/dx2) and also seeing the highest power i.e 3 but it is power of lower derivative dy/dx. According to the definition of differential equation, we should not consider highest power as order but should consider the highest derivative's power i.e 2 as order of the differential equation. Therefore, the order of the differential equation is second order.

What is second order differential equation?
The highest order of derivative is 2. There will be a second derivative {f''(x) or d2y/dx} in the equation.

What is the difference between a homogeneous and a non-homogeneous differential equation?
a linear first-order differential equation is homogenous if its right hand side is zero & A linear first-order differential equation is non-homogenous if its right hand side is non-zero.
What is the classification of a system of equations?
The answer will depend on what kinds of equations: there are linear equations, polynomials of various orders, algebraic equations, trigonometric equations, exponential ones and logarithmic ones. There are single equations, systems of linear equations, systems of linear and non-linear equations. There are also differential equations which are classified by order and by degree. There are also partial differential equations.
Why a constant is written after integrating?
Integration is the opposite of differentiation (taking the derivative). The derivative of a constant is zero. Integration is also called antidifferentiation since integration and differentiation are opposites of each other. The derivative of x^2 is 2x. The antiderivative (integral) of 2x is x^2. However, the derivative of x^2 + 7 is also 2x. Therefore, the antiderivative of 2x is x^2 + C, in general, where the constant C has to be determined from the context of the problem. In the above case, the constant happens to be C=7. We use integration to solve first order differential equations. When solving first order differential equations, like in "word problems", you must determine the integration constant using the initial conditions (ie the conditions we know to be true at t=0 - we usually know what these are), or the boundary conditions (ie the conditions we know to be true at x=0 and y=0).
