Intended for use in my AP Calculus BC class.[br][br]Drag sliders at left to set initial conditions for the projectile scenario. The unlabeled green slider causes the projectile to travel through its trajectory, from launch until impact with ground.[br][br]On some devices with a keyboard, it may be easier to select the slider and then use the arrow keys to nudge the values up or down.[br][br]Display is admittedly messy, but you should be able to drag objects around to resolve overlap/clutter.
