First, find a vector $a\, {\bf i}+b\, {\bf j}+c\, {\bf k}$ that is perpendicular to $8\, {\bf i}+4\, {\bf j}-6\, {\bf k}$. (Set the dot product of the two equal to 0 and solve. You can actually set $a$ and $b$ equal to 1 here, and solve for $c$.) Then divide that vector by its length to make it a unit vector.

given a non zero vector $\vec{u}=(a,b)=a\vec{i}+b\vec{j}$ the vector $\vec{v}=(b,\color{red}{-}a)$ is perpendicular to $\vec{u}$. the unit vector is then obtained by dividing by its norm $||\vec{v}||=\sqrt{a^2+b^2}$. so, the vector you seek is $$\left(\frac{b}{||\vec{v}||},\frac{\color{red}{-}a}{||\vec{v}||}\right)$$.

I need to find a vector that is perpendicular to the line $3x-4y=6$. I started with calculating slope of the line which I get $3/4$. A perpendicular line/vector would have a negative reciprocal slope if $-4/3$.

Jan 17, 2022 · In this video, we talk about how to find a unit vector perpendicular to another vector. We are going to present two ways to do this; one using dot product an...

Determine if the vectors \(\vec{u}=\langle 2,16\rangle\) and \(\vec{v}=\left\langle\frac{1}{2}, 4\right\rangle\) are parallel to each other, perpendicular to each other, or neither parallel nor perpendicular to each other.

Mar 29, 2024 · The Perpendicular Vector Calculator is a powerful tool designed to assist in mathematical, engineering, and physics problems by finding a vector perpendicular to a given input vector. This is particularly useful in 3D modeling, computer graphics, and spatial analysis, where understanding orthogonal relationships between vectors is crucial.

Consider foot of perpendicular from point to line; the distance from the point to this point is shortest distance from point to line; Calculate the direction vector of the line between the point and the foot, by using a parameter to represent the coordinates of the foot.

Feb 11, 2022 · I understand how to do this using right triangles: the length of my desired vector will be the magnitude of vector a divided by the cosine of the angle between vector a and the given unit vector. Once I find this value, I can simply scale the unit vector by this length.

Finding unit vector perpendicular to two vectors - Examples. Question 1 : Find the vectors of magnitude 10 √ 3 that are perpendicular to the plane which contains i vector + 2j vector + k vector and i vector + 3j vector + 4k vector. Solution : Let a vector = i vector + 2j vector + k vector. b vector = i vector + 3j vector + 4k vector
