This interactive figure graphs polar functions. It also serves as a resource to illustrate approximate values of [math]\frac{dy}{dx}[/math] at [color=#980000][b]any point[/b] [/color]on this function. [br] [br][b]Note:[br][/b]This figure uses the variable [i]t[/i] instead of the variable [math]\theta[/math][b][color=#38761d]. [/color][/b][br]To enter an exact value in the input box, such as [math]\frac{5\pi}{6}[/math] , type "5pi/6".
