Given vector a=(2,1), ab=10.,{ a+b }=5 times root 2. Then b=? 5+2*10+B^2b^2 Given the vector a=(2,1), ab=10.,{ a+b }= times root 2. Then b=? 5+2*10+B^2+b^2 Given the vector a=(2,1), ab=10.,{ a+b }=5 times root 2. Then b=? How do I get 5+2*10+b^2
|A+b|^2=a^2+2ab+b^2
50=5+2*10+B^2
B^2=25
|B |=5
Vector a=(1, m) b=(-2,4) and ab=-10, then m=
M=-2
1*4=-2*M
That's what I' m supposed to do. I haven't done this in a long time.

The result has a common unknown in the three components of the normal vector.
For example, if the result is (x,2x,4x), then the normal vector is (1,2,4).
In fact, if the plane is not parallel to the x-axis, the vector can be (1, x, y), and there are only two unknowns.
