    Rearranging parametric equations

    I'm much more confused now... Im not sure if your using different variables for the unknowns but it seems to change through out and is different then my original problem. In addition the two parametric equations are different then the given ones. Where did r and s come from? The original...

    Rearranging parametric equations

    So I got some sleep and took another look at what you wrote. Its makes sense to me up to a certain point. Here is what I've done so far: $$P_1=\left( \begin{array}{ccc} x_1 \\ y_1 \\ z_1 \end{array} \right) P_2=\left( \begin{array}{ccc} x_2 \\ y_2 \\ z_2 \end{array} \right) P_1=\left(...

    Rearranging parametric equations

    Ill have to go back through and re-read your method here but the two parametric equations are given in the first post. x=x0 + (x` - x0)t <-- I think this one is for the line x= x1 + (x2 - x1)u + (x3-x1)v <---- this one is for the plane Now I want to add that there should be arrows above all...

    Rearranging parametric equations

    Thanks for your reply. as simple as it may be im not sure how to go about equating the 3 equations. Maybe I'm not as familiar with parametric equations as I should be. For the line i have the coordinates: x0, y0, z0 x`, y`, z` For the plane I have: x1, y1, z1 x2, y2, z2 x3, y3, z3 I see...

    Rearranging parametric equations

    I wasnt planning on using maple or Matlab. But I do have some online tools and my TI-89 if the determinants or any of those operaitons become too much to do by hand. However all of the information thats given to me is in the first post. Im still tinkering with this one...

    Rearranging parametric equations

    Thats what I found as well so i feel I am doing something wrong to get the equations needed....Can I create another equation with substitution? sounds weird to say so im going to guess not but I've been playing with the equations for a little while now... Thanks for your reply.

    Rearranging parametric equations

    After looking at this a bit further perhaps im making it more complicated then it really is. I can simply rearrange to the following: x-x0 = (x` - x0)t + 0(u) + 0(v) x-x1 = 0(t) + (x2-x1)u +(x3-x1)v If this is the case then I need to see how to apply cramers rule to a 2x3 matrix....if possible

    Rearranging parametric equations

    Homework Statement I am given a line that passes through the points (x0, y0, z0) and (x`,y`,z`) and a plane in 3D space being defined by these three nonlinear points (x1, y1, z1), (x2, y2, z2), (x3, y3, z3). Im directed to use cramers rule to find the intersection of the line and plane...

    Microcode and microstore in VHDL?

    Ok, I understand. I still cant seem to find any information about the code presented above. Specifically what the "$" and "%" symbols mean in vhdl language and the "ORG" line at the beginning. The best I can guess with the information ive found is that it is a 4 bit memory string. But thats...

    Microcode and microstore in VHDL?

    Thanks for your reply. Im looking through the reference link you posted but i dont see any mention of memory,microcode or microstore. I downloaded the handbook that is linked to that site and am going through that as well. No hits on microstore or code but im looking through various sections...

    Microcode and microstore in VHDL?

    Is it safe to assume this is a term my professor created?

    Microcode and microstore in VHDL?

    Homework Statement So i am trying to understand what Microcode is in VHDL terms or Microstore for that matter. My course's lecture is a bit weak and i do most of my learning through text books that I have access too and researching online. However when I search for microcode online I come up...
