The sinus function is **y = sin(x)**. The graph of the sine function is called a sine wave. This is a curved line, repeated on certain sections, that is, a periodic. The period of the function T= 2π. The graph starts at the point (0;0).

The scope is all valid numbers. The value domain is [-1;1].

Example graph sinus function:

y=sin(x)

**y = -sin(x)**– the chart is shown horizontally

**y = sin(2x)**– the graph is “compressed” and the period is defined as T= π

**y = sin(1/2x)**– graph “expands” and period – T= 4π

**y = sin(x)+2**– the graph is shifted along the Y axis by 2 steps;

**y = sin(x+2)**– the graph is shifted along the x-axis by 2 steps

All graphs are built with our **graphical calculator**
