Suppose a vending machine contains products, and users insert coins into the vending machine to purchase products. How would I draw a UML diagram showing the dependencies between the classes VendingMachine, Coin, and Product?

There could be more than one model depending on the understanding of the relations between the classes.
A simple one would have to model the Customer as a class too. In this case, you will have the following relationships:
VendingMachine - Coin (because the vending machine receives coins)
VendingMachine - Customer (because the customer interacts with the vending machine)
VendingMachine - Product (because the vending machine has the products)
Customer - Coin (because the customer insert coins into the vending machine)
Customer - Product (because the customer wants to acquire a product)
The diagram can be found on page 14 in the source [1]
A more complex model can be found in the source [2]

Actually, the vending machine could give a rat's petunia where the coins came from. In most completed diagrams the customer interacts with a vending machine. The vending machine has all the processing.
Vending machine is many UML books. Google to find more.
