xstart or xfinish for 2D graph as a variable?
Hi,
Say I have the graph y = 2k and I want to plot this for x between a and 0 (this is part of STEP I 2011 Q13) I can enter the equation y = 2k and k is created as a variable. I then click on "Startup options" and set "Manual / xstart" to "a" rather than a specific numeric value. I set xfinish = 0. Now the default value for any variable = 1, so that may be the problem. Anyway, Autograph replaces "a" to 6 and plots the horizontal line between x=6 and x=0. I can't seem to make xstart or xfinish a variable. Is there any way to achieve this? Regards Clive
