SINE AND COSINE (GRAPH)
The sine and cosine graphs are wave-like curves that repeat every 360 degrees (or 2π radians). The sine graph (y = sin(x)) starts at the origin (0,0), rises to 1 at 90 degrees (π/2), returns to 0 at 180 degrees (π), drops to -1 at 270 degrees (3π/2), and completes the cycle at 360 degrees (2π). The cosine graph (y = cos(x)) starts at 1 at 0 degrees, drops to 0 at 90 degrees (π/2), reaches -1 at 180 degrees (π), returns to 0 at 270 degrees (3π/2), and completes the cycle at 360 degrees (2π). Both graphs have an amplitude of 1 and a period of 360 degrees (2π radians). Let me know if you need further clarification!
