Stretching the y=1/x graph
Loading the math board and drawing, please wait…
This example demonstrates how to transform the y=1/x function graph through integral manipulation. Key math concepts include function graph transformation, integral calculation, and logarithmic function properties. GeoGebra commands/objects used in construction are Segment (line segment) and Integral (integral). Suitable for high school and above students to understand the geometric meaning of function integration and transformation.
GeoGebra Commands & Parameters
Segment(A, B) → cSegment(C, D) → dIntegral(f, b, (a * b)) → areaIntegral(g, 1, a) → origarea
AI Drawing Prompt Reference
Draw a coordinate plane showing the graph of y=1/x in the first quadrant. Above the curve, construct a rectangle bounded by two horizontal and two vertical line segments, extending from x-coordinate b to the product of a and b, and shade this region to represent the definite integral of the function over that interval. Below the curve, from x=1 to x=a, shade another region bounded by the curve and the axes, representing the original integral. Clearly label both shaded areas to illustrate how the function graph is stretched through integral manipulation.
