SS 2 Graphs of Trigonometric Functions Mathematics SS 2 Second Term Introduction to Trigonometric Graphs Trigonometric functions (sine, cosine, and tangent) can be represented graphically. These graphs are periodic, meaning they repeat their values at regular intervals. 📌 Key Concepts: Period: The length of one complete cycle of the graph. Amplitude: The maximum displacement from the central axis (for sine and cosine). Frequency: The number of cycles completed in a given interval. Phase shift: T [Preview only]
