vektorväärtuslik
vektorväärtuslik is a Finnish term that translates to "vector-valued" in English. It refers to a function or a quantity that outputs a vector. In mathematics and physics, a scalar-valued function assigns a single numerical value to each point in its domain, while a vector-valued function assigns a vector to each point. For example, a function describing temperature in a room might be scalar-valued, assigning a single temperature to each location. In contrast, a function describing the wind velocity in the same room would be vector-valued, as it needs to specify both magnitude and direction at each point.
The concept of vector-valued functions is fundamental in various fields. In multivariable calculus, these functions are
