-        "we want both of them for iD on\nthe left-hand side expressed", 
-        "as a function of vD.",

-        "This little circuit here\ncontaining the Thevenin", 
-        "equivalent and connected to\nthe device, equation 2 is",

-        "iD and vD into some\nrelationship.", 
-        "This constraint that I&#39;ve\nplotted here as equation 2 is", 
-        "simply the constraint imposed\nby this device.", 
-        "OK, next, let me\ngo to 1 prime.", 
-        "And in 1 prime, let\nme go ahead and", 
-        "plot the 1 prime equation.", 
-        "And that equation, as we\nrewrite that here, is V", 
-        "divided by R minus vD divided\nby R. So I&#39;m just going to", 
-        "plot that equation for you\nin a second graph.", 
-        "So how do I plot this?", 
-        "So notice here that when vD is\n0, then iD is V divided by R.", 
-        "So that is one point on\nthe straight line.", 
-        "Notice that this is an equation\nfor a straight line.", 
-        "It&#39;s a linear relationship\nbetween iD and vD.", 
-        "Next, when iD is 0--\nso when iD is 0--", 
-        "then notice that R and R can be\ncanceled out, and V will be", 
-        "equal to vD.", 
-        "So when iD is 0, V\nand vD are equal.", 
-        "So therefore, vD equals V. So\nthis is the line when iD is 0.",

-        "straight line for the\nrelationship between vD and iD", 
-        "according to 1 prime.", 
-        "So what&#39;s the slope\nof this line here?", 
-        "Can you tell me what the\nslope of this line is.", 
-        "Let me give you a few seconds\nto think about it.", 
-        null, 
-        "OK, from the equation 1 prime--\nfrom this equation--", 
-        "the slope is simply given by the\ncoefficient of vD, since", 
-        "the slope is negative, which\nis why the line is inclined", 
-        "the following way.", 
-        "So the slope here is simply\nminus 1 divided by R.", 
-        "So that is my constraint\nthat relates vD to iD.", 
-        "And where did that constraint\ncome from?", 
-        "That constraint is the\nconstraint on iD and vD that", 
-        "has been imposed by the\nrest of the circuit.", 
-        "So if the first constraint was\nimposed by the device, then", 
-        "the second constraint is\nimposed by the Thevenin", 
-        "equivalent that is connected\nto the device.", 
-        "The Thevenin equivalent was\nthat V and R in series and", 
-        "those two impose a Thevenin\nconstraint on the terminal", 
-        "pair that relates vD and iD.", 
-        "So now my next step is,\ngiven these two graphs", 
-        "for iD versus vD--", 
-        "and clearly those are\nmy two constraints.", 
-        "Graph 2 says that iD and vD\nmust be somewhere on this", 
-        "trajectory.", 
-        "Graph 1 prime says, well, I&#39;m\nnot going to let vD and iD be", 
-        "anywhere else but\non this curve.", 
-        "That&#39;s it.", 
-        "Both of them are fighting with\neach other and telling each", 
-        "other, nope, I&#39;m not going to\nallow you to do anything.", 
-        "You have to be on my curve.", 
-        "So in this case, I have two\ncurves, and I need a point", 
-        "that satisfies both curves.", 
-        "And that is easy enough to do.", 
-        "And I simply have to go\nand satisfy both these", 
-        "constraints, and that will\ngive me the answer", 
-        "for vD versus iD.", 
-        "Before I do that, so I can go\nand solve it for you, let me", 
-        "go and pick some values for\nthe various parameters.", 
-        "So as before, I&#39;m going to pick\nV equals 1 volt, R equals", 
-        "1 ohm, a, a quarter of an amp,\nand b to be one volt inverse.", 
-        "So I&#39;ll pick the same parameters\nas I had done when", 
-        "I did the analytical method.", 
-        "Next, what I&#39;ll do is I&#39;ll\nsubstitute these parameters", 
-        "into the two equations 1 prime\nand 2 and rewrite them with", 
-        "the parameters substituted.", 
-        "So for 1 prime, I get iD.", 
-        "Since V is 1 and R is 1, I get\nV divided by R equals 1.", 
-        "And then since R is\n1, I get minus vD.", 
-        "So this is 1 prime, once I&#39;ve\nsubstituted the values.", 
-        "And then for equation\n2, what do I get?", 
-        "I get iD equals ae\nraised to bvD.", 
-        "a is 1/4, so I write\nthat down.", 
-        "b is 1, and so I\nget vD up here.", 
-        "So I have my two equations in\nterms of the parameters I have", 
-        "chosen, and now I can go ahead\nand plot the two equations and", 
-        "see where they intersect.", 
-        "I&#39;ve given you the form of the\ngraph here, and so let me go", 
-        "ahead and plot this.", 
-        "Let me go ahead and plot 2\nfirst. 2 looks like this,", 
-        "where this point is 1/4.", 
-        "That was the a point.", 
-        "As I said before, this curve\nis simply my Equation 2.", 
-        "Then let me go ahead and\nplot equation 1 prime.", 
-        "And as you recall, that looked\nsomething like this where the", 
-        "vD intercept was V and the\ny-intercept was given by V", 
-        "divided by R.", 
-        "And in this case, it was\n1, and V was also 1.", 
-        "So those are my two curves, and\nhere&#39;s the point where the", 
-        "two coincide.", 
-        "And then I just have to go and\nfind the values of iD and vD", 
-        "where they two intersect.", 
-        "So at this point, it will be\n0.56 volts, and this point", 
-        "will be 0.44 amps.", 
-        "It&#39;s the same as what\nI calculated in", 
-        "the analytical method.", 
-        "So let me go ahead and write\nthat down. iD equals, in this", 
-        "case, 0.44 amps, and vD\nequals 0.56 volts.", 
-        "So basically, I&#39;ve just\ntaken the two graphs,", 
-        "superimposed them.",
