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...
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(...
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...
Thanks for your reply.
as simple as it may be I am 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...
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 that's given to me is in the first post. I am still tinkering with this one...
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 I am going to guess not but I've been playing with the equations for a little while now...
Thanks for your reply.
After looking at this a bit further perhaps I am 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
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...
Ok, I understand.
I still can't 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 I've found is that it is a 4 bit memory string. But that's...
Thanks for your reply. I am looking through the reference link you posted but i don't 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 I am looking through various...
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 textbooks that I have access too and researching online. However when I search for microcode online I come up...
