mathswithmuza on Instagram: "The sine curve is one of the most fundamental graphs in mathematics, describing periodic oscillations that repeat smoothly over time. It arises naturally in contexts like sound waves, light waves, and circular motion, where values fluctuate between a maximum and minimum in a regular cycle. The standard sine function, y = sin(x), begins at zero when x = 0, rises to 1 at π/2, falls back to zero at π, dips to –1 at 3π/2, and then returns to zero at 2π, completing one fu
