*this is in response to Miss P Jones comment, its unlikey to be of use to you but perhaps other students who read it can understand: that example wasnt totaling the area of the curve, it was just calculating the integral, which isnt the same thing, the integral can be used in the manner you described to find the area under the curve, but that isnt the only use of the integral, nor is it the actual method you use if u were to just find the integral
Slide 8, part b), why is it not 1/2 +1/2 = 1?
When we total the area under a curve, if part of the curve is below the x-axis we always ignored the sign. Why is this different here?
Page 10 - integral at bottom of page - limits should be the other way round.
Check line 3 of the solution on slide 21 (should end up being minus 1/4)
