In algebra what does x mean
WebBroadly speaking, undefined means there is no possible value (or there are infinite possible values), while indeterminate means there is no value given the current information. For example in the equation ax + by = c, the relation between x and y is indeterminate because you can't determine it without knowing the values of a, b and c. WebYou can think of these subscripts simply as labels to keep the positions straight, just as we can use x 1, x 2, x 3 for an ordered triple representing a point in 3 -space. From a more formal point of view, however, a sequence is actually just a function. For example, the sequence x 0, x 1, x 2, x 3, …

So, the way we write "X multiplied by itself" with vectors (or matrices) is not X ⋅ X, but X ′ ⋅ X, so everything has the right shape. Of course, we don't need the dot in between, so it just comes out as.
