A vector is an object that has both a magnitude and a direction. Geometrically, we can picture a vector as a directed line segment, whose length is the magnitude of
DefinitionsVector a geometric object with magnitude (length) and direction, represented by an arrow.Collinear points points that lie on the same lineUnit vector vector with magnitude 1 Base vector 3.1.
For any polynomial of form anxn + an−1xn−1 + ··· + a2x2 + a1x + a0 = 0:Sum of roots Product of roots: Example: Given x2 + 8x + k
The fundamental theorem of algebra any polynomial of degree n has n roots. A degree of a polynomial is the largest exponent. Example: If f(x) = 4x3 + 3x2 +
