I fixed this error over a year ago but apparently forgot to reupload...

Just adding my voice to those highlighting the error on part b of slide 10. In general though thank you for the great powerpoints. In the end I decided to do it with my class anyway and asked them to find the angle between the vectors using the cosine rule as well, and then explaining the discrepancy between the two answers, really helped to cement where the 'angle with the x-axis' really was.

I agree with D Bareau on slide 10 as you can't find the area of triangle OAB with working done! On a positive note, great resources.

Sorry was using the vectors at the top of slide 10, i agree with 0.5sqrt(35)

I agree with D Bareau but the solution is not 0.5sqrt(35) it is 2.5root(65)

I agree with D Bareau about slide 10. Other than that a fantastic resource as usual!

Ah was just about to comment the same as D Bareau. I got confused and had to plot it on Geogebra to convince myself!

Slide 10. Triangle OAB area cannot be done with the method shown (the angle OA makes with the x axis and OB makes with the x axis cannot be subtracted to make angle BOA as they're not all on the same plane. The triangle's area should be half of root 35. Cheers.

Slide 8: reads root 41 instead of root 21 :-) Great resource, thanks. My year 12s are doing the new Alevel in one year so your slides are most welcome!

Excellent as always ... are resources for Mechanics 1 and 2 going to be released at some point?

Your resources are brilliant but I suspect the multiplier in slide 8 is -2 rather than 2. Many thanks Dr Frost
