- I really need to know how to get to the expression for DeltaU using "the full differential", rather than just a formula, this is helpful to confirm answers but it doesn't answer the actual question on how to get to the expressions for DeltaU for the Van Der Waals version of the equation since you had to come up with it in an integral yourself. More help maybe?Use Figure 1.11 to construct the cyclic rule equivalent of Does the answer make sense in light of the original partial derivative?Evaluate the operations in parts a, b, and f in the previous problem.
