Sin, Cos & Tan Visualizer — Unit Circle & Wave Graphs
Drag the angle and watch the unit circle, sine wave, and trig values update instantly
Enter any angle and see its sine, cosine, and tangent values plotted live on a unit circle alongside the wave graph, so you can build real intuition instead of memorizing a table.

How to use
- Drag the angle slider (0–360°).
- Read the live sin, cos, and tan values.
FAQ
- Does it show the radian value too?
- Yes, both degrees and the equivalent radian value are displayed side by side.
- Can I enter angles below 0° or above 360°?
- Yes. Angles are normalized internally, so values like -90° or 450° return the same trig results as their equivalent angle inside 0–360°.
- Why does the tangent value spike or disappear near certain angles?
- Near 90° and 270° the cosine approaches zero, which sends tangent toward infinity — that's why the curve appears to break or shoot off the chart there.
