1
Q
how to calculate the distance between a point and a plane?
A
- Label the A,B C values
- label the xo,y0,z0 values
- use the distance between a point and a plane formula to calculate the distance
2
Q
what is the distance between a point and a plane formula?
A
d=|Axo+Byo+Czo+D|/square root A^2+B^2+C^2
3
Q
how to determine the distance between two planes?
A
- find a point on the first plane
- use the point, the other plane, and the distance between a point and a plane formula to calculate the distance
4
Q
how to find the equation of a plane midway between two planes?
A
simply add the two planes together
5
Q
how to determine the coordinates of the equidistant for the two planes
A
find coordinates that make the answer for the two planes added up true
6
Q
how do you make an equation of a plane given three points?
A
lets say the points as A,B and C
- find the vector of AB
- find the vector of AC
- take the cross product of the two vectors and label the answer (a,b,c)
- use the equation a (x-xo)+b(y-yo)+c(z-zo)
7
Q
how do you determine the value of A given a point, a cartesian equation and the distance?
A
- write the distance between a point and a plane formula
- plug in the values you know
- isolate for A
8
Q
how to do you determine the distance between two planes?
A
- write the direction vectors of both the planes, label them m1 and m2
- take the cross product of the two direction vectors, label the answer (A,B,C)
- use the direction vector and a point from the first vector equations to isolate for D, and form a cartesian equation
- use the cartesian equation, the point from the second vector equation and the distance between a point and a plane formula to find the distance
