Do you have permission to use that graphic? Also, I assume that your other solutions for this exam are copied from Shawn's solutions, so ditto in case you used his workings verbatim. (Yes, I know you can't copyright 2+3=5 or d/dx(sin x)=cos x, or whatever, but if your steps are identical, then, I think it's not right to copy this without attribution.)

Hi Ziming,

As I mentioned below, please add words between equations for Question 1 (e) in MATH110 (2017).

You can at least mention which rules you are using. If there's not much thing to say, then please place two equations in one line, like .

Also, to avoid students' confusion, please put \cdot between two fraction for example in . Plus, it looks really better if you use \left( \right) when a fraction is in the bracket.

Thanks, Hyunju

Hi Ziming,

The detailed equations are really good, but it would be very helpful for students if you add more words between equations, instead of arranging several equations without words. It would be easier if you assume that you are explaining the solution in the class or in the MLC.

I editted Question 1(d) in MATH110 (2017), so you don't need to revise it further :)

Best, Hyunju

Hi Ziming,

According to your solution, (c) can also be the answer. Can you explain why (c) is excluded?

Best, Hyunju

Hi Ziming,

Thanks for writing hints and solution for MATH 110 (2017) :)

For the question 01 (b), it would be great if you write more explanatory; Especially at the last line, adding more words as below would be really helpful for the student; In this problem, , , so g(a) = g(1) = ..... and g'(a)= g'(1)=.... Therefore, plugging these to tangent line formula, we have .

Can you edit the solution a bit? Thanks!

Best, Hyunju
