Question 1(d) in MATH110 (2017)
From User talk:ZIMINGYIN
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
