Effect of Reflections on the Derivative
Loading the math board and drawing, please wait…
This example demonstrates the effect of reflections on the derivative of a function. By observing the derivatives of different functions and their reflected counterparts, students can understand the geometric meaning of derivatives and how reflection transformations affect the function and derivative graphs. The example primarily uses the If command to define the reflected functions and the derivative command f' to plot the derivative graphs. Suitable for high school mathematics education and learning calculus concepts.

If(a ∧ b, (-((-x^(3)))), a, (-x^(3)), b, ((-x))^(3), x^(3)) → fIf(a ∧ b, (-2^((-x))), a, (-2^(x)), b, 2^((-x)), 2^(x)) → gIf(a ∧ b, (-sin((-x))), a, (-sin(x)), b, sin((-x)), sin(x)) → h
AI Drawing Prompt Reference
Draw the function f(x) = x^3 and its reflection f'(x) = -x^3 across the y-axis, then draw the function g(x) = 2^x and its reflection g'(x) = 2^-x across the y-axis, and finally draw the function h(x) = sin(x) and its reflection h'(x) = sin(-x) across the y-axis. Observe the images of these functions and their reflections to understand how reflection transformations affect the function and derivative graphs.
