Discover the fundamentals of vectors and perform vector operations. Apply norm, distance, and orthogonal projection in Cartesian and n-space, including dot product, cross product, and parametric equations.
Define a vector as an arrow representing direction and magnitude, with equal vectors sharing the same length and direction, denoted by its initial point and terminal point.
Learn vector operations defined geometrically, including addition via parallelogram and triangle rules, subtracting using minus v, and scalar multiplication by k in two- or three-space.
Define vectors in two- and three-dimensional coordinate systems and determine their components from initial and terminal points using x2−x1, y2−y1, and z2−z1.
Define real n-space and ordered n-tuples, establish vector equality by component, and perform vector operations such as addition, scalar multiplication, negation, and subtraction with concrete examples.
Explore the norm of a vector in n-space as the square root of the sum of squares, and measure the distance between vectors as the norm of their difference.
Learn to compute the dot product as the euclidean inner product in rn, where u dot v equals the sum of ui vi for orthogonality testing.
Learn to decompose a vector into a projection along a and a component orthogonal to a, and compute it with the formula (u·a)/(||a||^2) a, plus the orthogonal remainder.
Learn the norm of the orthogonal projection of u onto A. Use the formulas ||proj_A(u)|| = |u·A|/||A|| or ||u|| cos theta, with a concrete example u=(2,-1,3), A=(4,-1,2).
Learn to express lines and planes with parametric equations, using x = x0 + t v for lines and x = x0 + t1 v1 + t2 v2 for planes.
Compute the cross product of three-dimensional vectors using determinant notation, and relate its norm to |u||v| sin θ, illustrating parallelogram and triangle areas.
