🔑Vectors are one-dimensional quantities that represent magnitude and direction.
🔑Two-dimensional vectors have two axes, allowing us to represent coordinate positions in a plane.
🔑Vectors are used in a wide range of applications, from space transformations to velocities and positions.
🔑The dot product of two vectors can be used to find the projection onto one vector.
🔑The order of the vectors does not affect the dot product, as long as one vector is normalized.
What is the dot product of two vectors?
—The dot product is an operation that gives the projection of one vector onto another.
How are vectors used in real-world applications?
—Vectors are used for space transformations, velocities, positions, orientations, and more.
Does the order of vectors affect the dot product?
—No, as long as one vector is normalized, the dot product will give the same result.
Can vectors be used in 3D geometry as well?
—Yes, vectors can be extended to three dimensions, allowing for more complex calculations and representations.
Are there any other operations involving vectors?
—Yes, there are other operations such as cross product, vector addition, and vector subtraction.
