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 Slider option and choose Slider No. 1 from the drop down list. To make the available sliders visible, check View -> Show Sliders Now you can move the slider and see how the parameter value modifies the position of the curve. Screenshots Input Show sliders option Slider window 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 angle. Define a constant 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 Slider option and choose Slider No. 1 from the drop down list. To make the available sliders visible, check View -> Show Sliders Now you can move the slider and see how the distance depends on the parameter value.
