Where did the s = s0 + Δs(T) equation come from?

Homework Statement 1- Use the thermodynamic table to establish an equation giving the molar entropy of liquid water as a function of temperature. Do the same for water vapor. 2- Use these equations to calculate the entropy of vaporization and the enthalpy of vaporization. 3- From the...

Ah that I forgot about that cosine property and I found a convenient sign mistake half way through the problem. Thanks Vela!

Thanks for the reply Vela! Actually I think I figured it out. Maybe you or someone else can check my work? I assumed that it the phi's were not typos, but they could very well be. I went ahead and attached my work.

Homework Statement See Attachment Homework Equations None I can think of The Attempt at a Solution I'm fairly certain that phi_yx is zero Also I tried factoring out the cos and splitting up the equation into it's respective components, but to no avail. Am I even going about this correctly?
