Investigate the relationship between gradient and the angle of inclination ([math]\theta[/math])

1) Move the sliders and observe what happens to the gradient and [math]\theta[/math].[br][br]2) Using the graph, fill the missing gradients of line AB for the below values of [math]\theta[/math]. [br][br]3) In your own words, explain what you are observing about the relationship between the angle of inclination and the gradient?
