Parabola

y=x^2

This quadratic has a vertex at the origin and is symmetric about the y-axis. Try y=x^2-3 to move it down.

y=2*sin(x)

In radians, the amplitude is 2 and the period is 2π. Angle mode changes trigonometric interpretation.

x^2+y^2=9

This equation describes a circle centred at the origin with radius 3.

y≤x^2

The region includes the parabola and points below it. Change ≤ to < to exclude the boundary.

a=2
y=a*x

Enter these in separate rows, then adjust the slider to change the slope.
