# KmPlot/Using Sliders

A main feature fo **KmPlot** is to visualize the influence of parameters to the curve of a function.

## Moving a Sinus Curve

Let's see, how to move a sinus curve left and right:

- Create a new cartesian plot.
- Enter the equation
f(x,a) = sin(x-a)

- Check the option and choose from the drop down list.
- To make the available sliders visible, check

Now you can move the slider and see how the parameter value modifies the position of the curve.

## Trajectory of a Projectile

Now let's have a look at the maximum distance of a projectile thrown with different angles. We use a parametric plot depending on an additional parameter which is the angel.

- Define a contant v_0 for the starting velocity.
- Create a new parametric plot
- Enter the equations
f_x(t,α) = v_0∙cos(α)∙t f_y(t,α) =2+ v_0∙sin(α)∙t−5∙t^2

- Check the option and choose from the drop down list.
- To make the available sliders visible, check

Now you can move the slider and see how the distance depends on the parameter value.
