Derivations

[edward_qiao_3I]

Will there be any questions on quizzes or midterms asking us to complete derivations of equations we learn in class?

[Chem_Mod]

Only what I derive in class is 'fair game'.

The overwhelming main focus, as one can see from past quizzes and exams, are questions similar to the assigned homework questions.

My TA said things like derivatives and integrals are highly unlikely to be tested on since many people are not taking a calculus based math class.

I think you will be fine regarding the derivations, you will not have to know them as most of the equations needed will be given.

I understand that there will most likely not be a lot of deriving during this course, but just in case, I was wondering if anyone had any resources that they found particularly helpful with brushing up on their calculus. It never hurts to be prepared!

Kristen, I recommend Khan Academy for calculus review! There are lots of review videos on the khan academy website and their youtube page!

[Isabella_Pena_3D]

My TA said to focus on the resources given to us (like quizzes and book problems), so my guess is that if we are tested on derivations, it'll be one that someone went over in Lecture or discussion.

If it's any help at all a guide to integration of polynomials and of x^-1 (also known as 1/x) can be found on the constants sheet.

[Patrick Ricaflanca 2H]

I think most of what will be asked for is the manipulation of given equations to solve for problems.
For example, delta U= q+w; since w=-PV we can substitute it into the equation -> delta U= q - PV

[Daniel Cho 1F]

No you will not have to worry about derivations.

[Mannat Sukhija 1E]

From what I understand, Dr. Lavelle does the derivations in class so we can have a better understanding of where the equations we use come from. But if you would still like to study the derivations there is a set of link on the Chemistry 14B wesbite about common derivatives in chemistry, and it is very helpful!

[Wenqian_Deng_1L]

My TA reviewed the equations sheet that will be given to us for the quiz and he said that almost all the equations we need are on the sheet. The only equation we need to memorize is the one that calculates work when it's a reversible isothermal reaction, which is w = -nRT ln(V2/V1)

The second post is my answer. Surprised to see students ignoring my answer.

Not true. We use them in multiple derivations in class.

Please see course requirements at UCLA Registrar's Office:
"Enforced requisite or corequisite: Life Sciences 30B or Mathematics 3B or 31B with grade of C- or better."

This means Math 3A or Math 31A or LS 30A (all calculus classes) are completed, and Math 3B or Math 31B or LS 30B (all calculus classes) are also completed or taken at the same time as Chem 14B.

Please see the Math Assistance section I have created on my class website to assist students.

Correct all equations and constants are given.

But everything covered in class can be asked including concepts used in derivations, and derivations.

Why would I go to all the effort of spending considerable time in class covering material and not expect it to be tested ...

Yes, as stated many times, the main focus is the homework and problem solving. But theory can and will be asked and that includes everything covered in class.

Please see my previous posts on this.

Please see the Math Assistance section I created on my class website. This material is sufficient for the math needed and used in Chem 14B.

Correct.
But only the ones I cover in my lectures. See my many above posts on this.

Correct

[Chem_Mod]

No you will not have to worry about derivations.

Everything I cover in lectures can be asked. See my many posts repeating this answer.

The emphasis in all tests is the assigned homework. Just like it was in Chem 14A.

[Chem_Mod]

All constants and equations are given. Including w = -nRT ln(V2/V1).

If derivatives will be covered on the exams, will knowing the simplest formula/ setup of the derivative suffice, or will we have to know each step of the derivation process?

[YuniLee_1K]

I think since most of the derivations are based on prior knowledge and using substitution from other equations, it would be probable that you can look at the question asked, look at what you're given, and see what concepts they have in common in order to derive the equation!
