Page 2: Advanced Concepts and Numerical Approximations

This page delves into more advanced aspects of calculating the momentane Änderungsrate, focusing on numerical approximations and limit concepts.

The page presents a table or matrix of values, likely representing different approximations of the momentane Änderungsrate as the step size $h$ approaches zero. This method is known as the limit definition of the derivative.

Key points on this page include:

• The use of small increments $h$ to approximate the momentane Änderungsrate
• Values ranging from -0.999 to -1.01, suggesting a convergence towards -1
• The presence of very small values like 0.001 and 0.01, indicating precision in calculations

Vocabulary: "h" in this context typically represents the step size or increment used in numerical approximations of derivatives.

Definition: The momentane Änderungsrate is the limit of the average rate of change as the interval approaches zero.

Highlight: The table demonstrates how the approximation of the momentane Änderungsrate becomes more accurate as the step size $h$ decreases.

This page emphasizes the importance of understanding limit concepts in calculus and how they relate to finding the momentane Änderungsrate. It also illustrates the practical application of numerical methods in approximating derivatives when exact analytical solutions are not readily available.

Page 1: Calculating Momentane Änderungsrate

This page outlines two methods for calculating the momentane Änderungsrate (instantaneous rate of change): using a graphing calculator and without one.

Using a graphing calculator (ETR method):

1. Access the Matrix function
2. Use the Shift key
3. Navigate to the Menu
4. Select the Derivative option

Without a graphing calculator:

1. Plot the graph
2. Input the formula
3. Use the Shift function
4. Access F" (Sketch)
5. Select F2 (Tangent)
6. Enter the desired x-value
7. Read the slope of the tangent line

The page also includes a visual representation of a graph, illustrating a parabola with a tangent line. The slope of this tangent line represents the momentane Änderungsrate at the point of tangency.

Vocabulary: ETR likely stands for "Electronic Table and Regression" or a similar function on graphing calculators.

Example: The graph shows a parabola with the equation y = x² + 2x + 3, and the tangent line at a specific point has a slope of approximately 2x.

Highlight: The manual method without a graphing calculator emphasizes the importance of understanding the graphical representation of the momentane Änderungsrate.
