As students navigate the steep learning curve of the subject, the search for the becomes a common ritual. This search represents a student’s desire for clarity, verification, and sometimes, a lifeline in a difficult course.
“I have been working on problem 14.3 from Rice’s Applied Mathematics for Chemical Engineers , but I am stuck on the finite difference implementation. Could I see a worked solution or a hint?” As students navigate the steep learning curve of
[ C_i^n+1 = C_i^n + \fracD \Delta tr_i^2 (\Delta r)^2 \left[ r_i+1/2^2 (C_i+1^n – C_i^n) – r_i-1/2^2 (C_i^n – C_i-1^n) \right] ] As students navigate the steep learning curve of
