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 variable c times the variable b simply equals cb. Just as the variable x times the variable y would equal xy, and so on.

The answer depends on what R and C are.
