Nettet28. jan. 2024 · 7. In linear algebra, we learn that the inverse of a matrix "undoes" the linear transformation. What exactly is the meaning of the inverse of ( X T X) − 1? X T X we know as being a square matrix whose diagonal elements are the sums of squares. So what are we doing when we take the inverse of this? I have always used this property … NettetThe Δ symbol means "change in". Δx/Δt is the rate of change in x over the time interval. If we reduce the time interval so that it is smaller and smaller, the rate of change is going …
