Linear Algebra: Circles and Spheres
When dealing with circles and spheres in linear algebra, it can seem overwhelming with various symbols and coefficients. However, there is a way to bring order to the mess. One method is by understanding the components of a vector along the x- and y-axes. By visualizing these components, you can form a right triangle with the vector. This helps in computing the areas or volumes of circles and spheres more easily.
Example:
Let's say we have a vector A = (3, 4) which represents a point in 2D space. Ax and Ay would be the x and y components of A, which are 3 and 4 respectively. We can draw a right triangle with A, Ax, and Ay as the sides. This triangle helps us visualize the relationship between the vector and its components, making it simpler to compute the properties of circles and spheres.
