The key to resolving vectors into perpendicular components lies in the fact that they form a right triangle with the total vector. Since right triangles are involved, we can apply trigonometry.

What's interesting or what's useful about linear algebra is, we've just defined the triangle inequality for arbitrarily large vectors, or vectors that have an arbitrarily high number of …

Since vector addition forms a triangle, we can think about angles that are formed at the intersections. We know that the larger the angle, the larger the side opposite to it.

We can find the horizontal component A x and vertical component A y of a vector using the following relationships for a right triangle (see Figure 1a). A is the hypotenuse of the right triangle.

The key to resolving vectors into perpendicular components lies in the fact that they form a right triangle with the total vector. Since right triangles are involved, we can apply trigonometry.

Area between curves that intersect at more than two points (calculator-active) Volumes with cross sections: squares and rectangles (intro) Volumes with cross sections: squares and rectangles …

Review the key skills for angled forces, such as how to break down forces into the horizontal and vertical components.

In one of the practice problems, there is a vector diagram and three multiple choice options (c+b=a), (c+b=-a), and (a+b=c). The question to be answered is 'Which equation matches the …

- [Voiceover] Triangle ABC undergoes a translation, and we're using the notation capital T for it, and then we see what the translation has to be. We're gonna move, it's kind of small, I hope …
