Note that we can also use as the normal.
Then the plane equation is .
We can find simply by using one of the points.
Check it with another one of the points.
I've got this exercise where I'm required to describe the equation of the plane determined by the fact that the following
three points lie in it:
So we find two vectors that lie in the plane
To find a normal vector we need to take the cross product
The equation can now be rewritten to the form
I'm not sure how to reorganize that equation to evaluate the d mentioned above. Any help /push in the right direction would be great!
So we distribute out the left hand side.
If any mistakes can be pointed out and any help towards the completion of this exercise would be greatly appreciated.
Ok but the normal i've used is also correct isn't it?, along with my distrubiation of the LHS in the equation:
"We can find simply by using one of the points. Check it with another one of the points."
That i'm not sure of, how do you mean check it?.
