My math: f(theta)= as above f'(theta)= as above (1) tan line: y-z=f'(theta)*(x-theta) (2) perp line: y-z=(-1/f'(theta))*(x-theta) (3) d=sqrt((x-theta)^2+(y-z)^2) solve for y in (2) and sub into (3) d^2=(x-theta)^2+((theta-x)/f'(theta)+z-z)^2 Simplify d^2=(x-theta)^2*(1-1/f'(theta)^2)...

Hello, I am trying to fit a sine function to a general curve. Convolution isn't giving me what I want, which is for every point on a general curve, displace that point by another function. I have written some code in Octave, and it's close, but not quite it. What I did was to take a general...

Sorry about the delay. My question with the MBWR equation of state was determining the Volume from inside the summation. I can't directly solve for it, so I am assuming I need to put it into a guess and check routine until the error falls into an acceptable range?

Bump.

Right, I have that link as well. I can use the tables effectively, and I have found the properties at the conditions I needed (55/100)degF. My question is one of curiosity at this point. How to calculate it programmatically.

Hi all, Just for fun I am writing a program in Octave for calculating the thermodynamic properties of R-134a. I am using the equations in the Dupont properties booklet. http://www2.dupont.com/Refrigerants/en_US/products/Suva/Suva134a.html My functions for calculating the liquid density...
