Finally understand trigonometry. Touch Trigonometry is the most intuitive way to learn the trigonometric functions. Instead of memorizing formulas, you'll see how sin, cos, tan, and the rest actually work—by touching and exploring a live unit circle and graph. Drag your finger around the circle and watch trig functions respond in real time. You'll be amazed at how quickly the "true meaning" of trigonometry becomes clear. Watch the graph on the right trace their values. In seconds, concepts that confused you for years will suddenly click. This app is great for students struggling with trigonometry or anyone looking for a refresher. HOW IT WORKS On the left: an interactive unit circle. Touch anywhere and drag to change the angle θ (theta). A triangle forms showing the relationships between the angle and the trig values. On the right: live graphs of all six trig functions. As you move the angle, dots trace along each curve showing the current value. Touch the graph side to control the angle from there too. It's bidirectional, immediate, and intuitive. No tutorial needed—just touch and explore. Users have told us that they never understood *why* the trig functions existed—until they used this app. From students to the math curious, Touch Trigonometry offers a truly intuitive way to understand one of the trickiest parts of geometry—at your fingertips!
