WebThe favored aspect ratio of mass-market display industry products has changed gradually from 4:3, then to 16:10, then to 16:9, and is now changing to 18:9 for smartphones. The 4:3 aspect ratio generally reflects older products, especially the era of the cathode ray tube (CRT). The 16:10 aspect ratio had its largest use in the 1995–2010 period, and the 16:9 … WebA vector has magnitude (how long it is) and direction:. Here are two vectors: They can be multiplied using the "Dot Product" (also see Cross Product).. Calculating. The Dot Product is written using a central dot: a · b This means the Dot Product of a and b. We can calculate the Dot Product of two vectors this way:
WebTwo vectors a and b are orthogonal if they are perpendicular, i.e., angle between them is 90° (Fig. 1). рис. 1: ... Calculate the dot product of these vectors: a · b = 1 · 2 + 2 · (-1) + 0 · 10 = 2 - 2 + 0 = 0 Answer: since the dot product is zero, the vectors a and b are orthogonal. Example 5.
