In this video I go over the first 4 questions of the True-False Quiz on the Vectors and the Geometry of Space Chapter. These 4 questions are all false, and I discuss why for each question. The first falsely states that the dot product is a vector. The second falsely equates the length of a vector sum as the sum of its vector lengths. The third forgets the cosine function in the length of a dot product formula, and the 4th forgets the sine functions in the length of a cross product formula.
Time stamps:
