To construct a vector that is perpendicular to another given vector, you can use techniques based on the dot-product and cross-product of vectors. The dot-product of the vectors A = (a1, a2, a3) and B = (b1, b2, b3) is equal to the sum of the products of the corresponding compon...
Calculate the dot (scalar) product using the coordinates(2−a)(−a)+(4−b)(−b)=0Expand and simply and rewrite equation asa2+b2−2a−4b=0We next use condition 2) above using the square of the magnitude of vector →TC to be equal to the square of the radius.(0−a)2...
This means that the dot product of the two vectors is equal to 0. How do you find a vector perpendicular to another vector? To find a vector perpendicular to another vector, you can use the cross product. The cross product of two vectors will result in a vector that is perpendicular to...

In plain English: the perpendicular vector¯vv¯is found by taking the cross product ofuuwith the axis of its smallest component. (Note: the same care is needed when multiple components are the smallest.) Figure 3 visualises this intermediate ‘swizzle’ vector over the sphere: ...
