I might try: I think youve got your conditionals flipped, and that wouldnt fix - -, (Instead of the numericValues, you could make variables in the graph for |h| and |k|.). For example. Students use the sliders to create the circle and the equation appears floating above as a dynamic label. Is there a way that I can make my label conditional, so that I could change the form based on whether h . Yeah there are a few CL tricks you could do here. Label the equations based on the corresponding element it follows. I made a graph to generate cobwebs cause. uhm.. no , this isn't how you are supposed to play the game. Whether you're interested in form, function, or both, you'll love how Desmos handles parametric equations. 2 circles; 2 horizontal or vertical ellipses (or 1 of each) 1 vertical parabola; 1 horizontal or vertical hyperbola; 2 lines; 1 absolute value graph; one or more conic equations You should only need the first three functions to create a parametric sector. OK, with all your help, here is the code I came up with and it works PERFECTY (even drops the parenthesis when h or k=0). If you would like to know the co-ordinates of a point on the line, simply left-click on the point (and hold your mouse down). Is there a way that I can make my label conditional, so that I could change the form based on whether h and/or k are positive or negative.
