This article explains the basic concepts, applications, and benefits of learning the Modified Euler Method (Heun's Method). This method, a step forward from the simple Euler method, plays a very important role in the world of numerical analysis. 1. What is the Modified Euler Method (Heun's Method)? The Modified Euler Method, also known as Heun’s Method, is a numerical method for obtaining approximate solutions to initial value problems: dy/dt = f(t, y), y(t_0) = y_0 The traditional Euler method determines the next value, y_{n+1}, using only the slope of the tangent line at time t_n, namely f(t_n, y_n).  However, when the step size is large or the problem exhibits strong non-linearity, this can lead to significant errors. A key feature of Heun’s Method is its ability to achieve higher accuracy (local error of second order) through a two-stage evaluation process, improving upon the Euler method. 2. In What Scenarios is it Applied? Due to its simplicity and improved accuracy, Heun...

Here’s an in-depth blog post introducing the fundamentals of the Euler method, its practical applications, and the benefits of learning it. The Euler method is a simple yet profound numerical solution technique, particularly attractive for its ability to easily handle difficult-to-analyse differential equations. 1. What is the Euler Method? The Euler method is the most basic numerical method for approximately solving initial value problems. It approximates the evolution of a differential equation using linear approximations at small time steps, thereby determining the progression of the continuous solution in stages. While intuitive and easy to understand, the Euler method is prone to error if the step size is too large. Therefore, setting a sufficiently small step size is crucial for achieving adequate accuracy.  This method is also used as an introduction to numerical analysis and serves as a bridge to more advanced algorithms, such as Runge-Kutta methods. 2. Where is it Used? Du...

Here's an in-depth blog post exploring the basic concepts of interpolation, its practical applications, and the benefits of learning it. We encourage you to delve into the world of interpolation, a technique widely used in fields such as mathematics, science, and engineering. 1. What is Interpolation? Interpolation is a method for estimating unknown values that lie between known data points or function values. Essentially, given a set of discrete points, it’s a technique for smoothly connecting them to infer new values or the shape of a function. Common methods include linear interpolation, polynomial interpolation, and spline interpolation.  Behind the mathematical principles and calculations lies a deep connection to mathematical analysis and numerical computation, making it a highly practical and elegant technique. 2. Where is Interpolation Used? Due to its flexibility and accuracy, interpolation techniques are applied in a variety of fields. - Digital Images & Computer Grap...
