On the test they have on their site, there is a question (number 6 I think...) where you have to find the derivative of 3x^(n+2). I used the power rule and got (3n+6)^(n+1) which I believe works out. It was marked wrong(along with another I disagree with)...is it possible that someone else made the mistake and I do remember calculus???
[For anyone who is confused by the above comment, it doesn't actually have anything to do with "Example 2" in the interactive notes.]
This is the first time, we're running this course, so we're still working out the bumps. If you have a question like this, it may be best to simply email me, the tutor: dustin.freeman@gmail.com
On to answering the question...
You were right! I made a mistake in writing the quiz and the correct answer is (3n+6)^(n+1). Thanks for spotting the error. I will update this now.
What was the other question you thought was wrong?
Would you use limits to go about example 2? I'm pretty confused about general cases to begin with.
