Final answer:
To find f(x) x g(y), multiply the function f(x) = tan(x) - 2/x by the constant function g(x) = 12, which results in (tan(x) - 2/x) x 12.
Step-by-step explanation:
The question asks to find f(x) \times g(y), where f(x) is given as tan(x) - 2/x, and g(x) is a constant function given by 2² + 8, which simplifies to 12 since 2² equals 4 and 4+8 equals 12. The product f(x) \times g(y) thus becomes (tan(x) - 2/x) \times 12. Since g(y) is a constant, it does not change with different values of y, and the multiplication is straightforward.
Based on the snippets provided, the context appears to be related to physics, involving equations of trajectories, optics, and special relativity. However, these snippets do not directly influence the computation of the functions f(x) and g(y) as described in the question.
