Interactively control amplitude, frequency, phase shift, and vertical offset to see how each parameter independently transforms y = Asin(ωx + φ) + k.

Interactive visualization of sine and cosine waves from the unit circle. Manipulate amplitude, frequency, and phase to understand wave transformations.

Visualize arithmetic, geometric, and alternating sequences as discrete functions.

Explore the geometric landscape of best fit lines and the sum of squared residuals. Interact with regression lines to intuitively grasp the Method of Least Squares.
