Science talk:Math Exam Resources/Courses/MATH101/April 2013/Question 04 (a)

I think we need to see more of how the points of intersection were solved (students struggle with trigonometric equations).

Also, I think we need a few more steps in the computation; Something between when we're about to plug the endpoints in and just the final answer.

Oh man I completely forgot about the graph in this problem! lol this was pretty redundant - but thanks for this Vince!

... wouldn't hurt either - perhaps explaining how we figure out which curve is on top etc.
