Homework Statement
I cannot seem to find my textbook and we just started derivatives. Can anyone tell me when I would use the notation dy/dx as opposed to something like f'(x)??
Thanks!

The most common notation used for derivatives is the Leibniz notation, which uses the symbol d to represent the derivative and places it in front of the function to be differentiated. For example, d/dx represents the derivative of a function with respect to x.
The derivative of a function using the Leibniz notation is written as dy/dx, where y is the dependent variable and x is the independent variable. This notation is read as "the derivative of y with respect to x."
The Leibniz notation is beneficial because it clearly indicates which variable is being differentiated with respect to, making it easier to understand and work with. It also allows for multiple derivatives to be written in a single expression, such as d²y/dx² for the second derivative of y with respect to x.
Yes, there are two other commonly used notations for derivatives: Lagrange notation and Euler notation. The Lagrange notation uses a prime symbol (') to represent the derivative, while the Euler notation uses the symbol D. Both notations also indicate the independent variable being differentiated with respect to.
To determine the derivative of a function using notations, you must first identify which notation is being used. Once identified, you can use the appropriate rules and formulas to find the derivative. For example, in Leibniz notation, you would use the power rule for derivatives, while in Lagrange notation, you would use the chain rule.
