Rust Primer is something that will prevent rust. Not stop or get rid of it if you already have it. As others have said, there is no easy solution. I have a older car and tried that in my youth thinking the same with Rust primer.
The geometric mean is defined as the nth root of the product of n numbers, i.e., for a set of numbers, the geometric mean is defined as.For instance, the geometric mean of two numbers, say 2 and 8, is just the square root of their product; that is.he geometric mean of a data set is less than the data set's arithmetic mean unless all members of the data set are equal, in which case the geometric and arithmetic means are equal.
A tangent is an entirely different topic or direction. When you want a break from geometry class, you might ask your teacher about his hobby of woodworking, a topic that's always good for a ten-minute tangent. Tangent is mainly a mathematical term, meaning a line or plane that touches a curved surface but doesn't intersect it. The non-mathematical meaning of tangent comes from this sense of barely touching something: when a conversation heads off on a tangent, it's hard to see how or why it came up.
