What is a vector in the context of coordinates?
Click to flip
A vector is a quantity that has both magnitude and direction, often represented as an arrow in space.
Click to flip
How do you calculate the magnitude of a vector in 3D space?
Click to flip
The magnitude of a vector (a, b, c) in 3D space is √(a² + b² + c²).
Click to flip
What is vector addition?
Click to flip
Vector addition is combining two vectors by adding their corresponding components.
Click to flip
What is the result of multiplying a vector by a scalar?
Click to flip
Multiplying a vector by a scalar changes the magnitude and can reverse the direction if the scalar is negative.
Click to flip
What is the dot product of two vectors?
Click to flip
The dot product of vectors A = (a1, b1, c1) and B = (a2, b2, c2) is a1*a2 + b1*b2 + c1*c2.
Click to flip
When are two vectors considered to be orthogonal?
Click to flip
Two vectors are orthogonal if their dot product is zero.
Click to flip
What is the cross product of two vectors in space?
Click to flip
The cross product of two vectors is a vector that is perpendicular to both of the original vectors.
