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 an Airy equation?
An Airy equation is an equation in mathematics, the simplest second-order linear differential equation with a turning point.
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 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.

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.
What are the degrees of differential equation?
The degree of a differential equation is the POWER of the derivative of the highest order. Using f' to denote df/fx, f'' to denote d2f/dx2 (I hate this browser!!!), and so on, an equation of the form (f'')^2 + (f')^3 - x^4 = 17 is of second degree.

What is parabolic heat equation?
The parabolic heat equation is a partial differential equation that models the diffusion of heat (i.e. temperature) through a medium through time. More information, including a spreadsheet to solve the heat equation in Excel, is given at the related link.
Applications of second order differential equation?
Second-order differential equations are widely used in various fields, including physics, engineering, and finance. They model systems involving acceleration, such as mechanical vibrations, electrical circuits, and fluid dynamics. In structural engineering, they describe the deflection of beams under load, while in economics, they can represent dynamic systems like capital accumulation. Their solutions provide insights into the stability and behavior of these systems over time.
Main points of Legendre differential equation?
The Legendre differential equation is the second-order ordinary differential equation(1)which can be rewritten(2)The above form is a special case of the so-called "associated Legendre differential equation" corresponding to the case . The Legendre differential equation has regular singular points at , 1, and .If the variable is replaced by , then the Legendre differential equation becomes(3)derived below for the associated () case.Since the Legendre differential equation is a second-order ordinary differential equation, it has two linearly independent solutions. A solution which is regular at finite points is called a Legendre function of the first kind, while a solution which is singular at is called a Legendre function of the second kind. If is an integer, the function of the first kind reduces to a polynomial known as theLegendre polynomial.The Legendre differential equation can be solved using the Frobenius method by making a series expansion with ,(4)(5)(6)Plugging in,(7)(8)(9)(10)(11)(12)(13)(14)so each term must vanish and(15)(16)(17)Therefore,(18)(19)(20)(21)(22)so the even solution is(23)Similarly, the odd solution is(24)If is an even integer, the series reduces to a polynomial of degree with only even powers of and the series diverges. If is an odd integer, the series reduces to a polynomial of degree with only odd powers of and the series diverges. The general solution for an integer is then given by the Legendre polynomials(25)(26)where is chosen so as to yield the normalization and is ahypergeometric function.The associated Legendre differential equation is(27)which can be written(28)(Abramowitz and Stegun 1972; Zwillinger 1997, p. 124). The solutions to this equation are called the associated Legendre polynomials (if is an integer), or associated Legendre functions of the first kind (if is not an integer). The complete solution is(29)where is a Legendre function of the second kind.The associated Legendre differential equation is often written in a form obtained by setting . Plugging the identities(30)(31)(32)(33)into (◇) then gives(34)(35)
How is the heat equation derived?
The heat equation is derived from the principles of conservation of energy and Fourier's law of heat conduction. It describes how heat is transferred through a material over time. The equation is a partial differential equation that relates the rate of change of temperature to the second derivative of temperature with respect to space and time.
