The differential of the product xy with respect to x is y + x dy/dx. The differential of logy with respect to x is (1/y) dy/dx. The role of c in this question is not made clear.
Inverse proportion implies xy = c where c is the constant of [inverse] proportionality. x = 2 and y = 36 implies xy = 72 = c So the relationship is xy = 72 Then, if x = 4, y = 72/x = 72/4 = 18
y' = (sec(x))^2
The equation (xy = c), where (c) is a constant, represents a hyperbola in the xy-plane. To find the slope, we can implicitly differentiate the equation with respect to (x). This gives us (y + x \frac{dy}{dx} = 0), leading to the slope (\frac{dy}{dx} = -\frac{y}{x}). The slope varies depending on the values of (x) and (y), indicating that it is not constant across the hyperbola.
The variable c times the variable b simply equals cb. Just as the variable x times the variable y would equal xy, and so on.

In general, yes. However, if there is a drawing that goes along with this question, and it shows more information about 'c' that you have not bothered to share, then it's certainly possible that point 'c' may not lie in the same plane as 'xy'.

A.
2a. (a, b and c are all equal.)
a= (+a) or a= (-) b= 2a b= 2a c= (-a) c= (+a)
c
Yes.
The answer depends on what R and C are.
a - b = c -(a - b) = -c b - a = -c
