Mathematical Modelling

While i was doing my daily routine of reading the blog, I've seen some homework that were posted by my peers. I should say that I'm quite impress by the quality of their work. I'm starting to really like this bunch of people. I can see that they are really enthusiastic to learn math. Now, i kinda want to go to the class and meet all of them, so i left their homework some comments.

First of all good job on the detailed answer. I really like how you put a lot of space so your solution will be easy to follow.After doing the whole question myself, I therefore conclude that Zeph's answer is the right one. There is something wrong with the algebra. There are many different ways to check this problem. One of them is to use your calculator. First of all, you need to plug in the function. Then press the 2ND button then TRACE then press 1.After that plug in your answer as the x value then press ENTER. You should see that the y value should be very close to 4. Thats the quick way of doing it.


Here's another comment from another homework.

Great work everyone! I really like that your solution is easy to follow because of the added space. After checking your solutions, I therefore conclude that it is perfect. Now, I just need to check two more questions from the other groups.

Hi Mark,

I surely hope that a belated comment is better than none!

I wanted to commend you on the comments and assistance you are providing for your classmates. You've used a really good mix of a positive, reinforcing tone plus math expertise!

You mentioned when you began "Kind of weird trying to help my fellow classmates in their math studies based on my experiences and wisdom". Are you feeling more comfortable now that you've had more experience mentoring?

Best wishes,

Thanks for your positive feedback on my work. I feel like I'm more comfortable now that I've had more experience in mentoring. I definitely think that I've found the right mix of positive feedback, constructive criticism and some math expertise in my comments. Now, it just seems like I'm talking to my friends at school. It just comes so naturally now.
