Trig transformations • visual math studio

See how sine, cosine, and tangent actually move.

Adjust amplitude, frequency, phase shift, and vertical shift, then compare the transformed graph to the parent function. Use presets for quick examples, quiz mode for practice, or type your own values like a student solving homework.

Quick examples

Jump into a classic parent graph, a stretch, or a shifted trig function.

Choose the base function

Use sliders for intuition, then switch to student input mode to type your own values for A, B, h, and k.

Amplitude / vertical stretch (A)

Negative values reflect the graph across the x-axis.

Frequency / horizontal scale (B)

Changing B changes the period. Negative values reflect across the y-axis before shifting.

Phase shift (h)

Positive h moves the graph to the right in the form y = A f(B(x - h)) + k.

Vertical shift (k)

Moves the midline up or down.

Graph helpers

Blue dots mark transformed key points. Pink dashed lines show tangent asymptotes.
