Numerical differentiation can be a daunting topic for many students, but fear not! In this blog post, we'll simplify the process and guide you through a tough assignment question step by step. Whether you're new to the concept or just need a refresher, we've got you covered.

Before we delve into the assignment question, let's briefly discuss what numerical differentiation entails. In calculus, differentiation involves finding the rate at which a function changes. Numerical differentiation, on the other hand, is the process of approximating the derivative of a function using numerical methods. This is particularly useful when dealing with functions that are difficult or impossible to differentiate analytically.

Consider the function 𝑓(𝑥)=𝑒^𝑥. Your assignment is to approximate the value of 𝑓′(2) using numerical differentiation.

1. Select a Step Size: The step size, denoted as ℎ, determines the interval over which we approximate the derivative. Choosing an appropriate step size is crucial for accuracy. For this example, let's choose ℎ=0.1.

2. Choose a Numerical Differentiation Method: There are several numerical differentiation methods, each with its own advantages and limitations. For simplicity and effectiveness, we'll use the central difference method.

3. Apply the Central Difference Method: This method involves calculating the slope of the tangent line at a point by considering function values on either side. Without diving into the mathematical formula, let's break down the concept: we'll compute the slope between two points close to 𝑥=2, namely 𝑥=1.9 and 𝑥=2.1, and take their average.

4. Plug in the Values: Using the function 𝑓(𝑥)=𝑒^𝑥, evaluate 𝑓(1.9) and 𝑓(2.1). Then, calculate the difference between these values and divide by 2ℎ2h to approximate 𝑓′(2).

Interpret the Result: Once you've computed the numerical approximation, take a moment to understand what it means in the context of the function. In this case, 𝑓′(2) represents the rate of change of the function 𝑓(𝑥)=𝑒^𝑥 at 𝑥=2.
