sorry I am so dumb, coz i forgot all maths over the holidays..
but if y = x/z
then how do you calculate dx/dy?

The notation "dx/dy" represents the derivative of the function y with respect to x. In other words, it measures the rate of change of y with respect to changes in x.
To calculate dx/dy, you first need to express the given equation in terms of x and y. Once the equation is in the correct form, you can use the rules of differentiation to find the derivative. Specifically, you can use the quotient rule, which states that the derivative of y/x is equal to (x * dy/dx - y * dx/dx)/x^2. Simply plug in the values for x, y, and z to calculate dx/dy.
Yes, the value of dx/dy can be negative. This indicates that as x increases, y is decreasing at a certain rate. In other words, the function is decreasing with respect to x.
dx/dy is equal to 0 when the rate of change of y with respect to x is 0. This means that the function is not changing at that point and is either at a local maximum or minimum.
The value of dx/dy at a given point on a graph represents the slope of the tangent line to the curve at that point. This means that dx/dy gives us information about the steepness of the graph at a specific point.
