???? Theory: Trigonometric Graphs
Trigonometric functions describe angles and periodic phenomena. Their graphs reveal properties like amplitude, frequency, phase, and vertical shift.
- Sine/Cosine: Periodic wave with amplitude.
- Tangent/Cotangent: Periodic with asymptotes.
- Secant/Cosecant: Reciprocal curves with discontinuities.
- Arcsin: Inverse of sine, limited domain and range.
