Designed to accompany the Pearson Applied Mathematics Year 1/AS textbook.
I've reuploaded to replace the dolphin equation.
I changed the equation of the dophin graph to v= - t^3-4t^2+11t+2 so it made more sense
Fantastic resources and just perfect to help students who are continuing A level study from home during this time.
Excellent resource, thank you. Only error is that the dolphin's velocity is initially decreasing and the answer given is a local min.
Can't begin to describe how many hours you have saved me, thank you!
Can you change the dolphin question though? It doesn't make sense!
I've fixed the Pudding error.
Pudding the cat question on variable acceleration should be -36t if (b) and (c) are correct. In which case (a) needs correcting. But thank you for brilliant slides. Just thought it was good to know.
I found the slides very helpful, so upload more now.
hello sir can you do a compilation of exam questions by topic
Can you do year 2 mechanics as well please?
Thanks for the hard work! I think there is a problem with Pudding the Cat (actual quadratic has no solutions; should be fixed by turning last term into '-36t'). Also the dolphin question (slide 9) doesn't quite work as the stationary point given as the answer is actually a local minimum; the max occurs at t = -2. Also the speeds are unrealistically high for a dolphin which I find funny, but my colleague is a marine biologist and she thinks you should change it. It led to a great chat with my class and plenty of laughter about the sorts of things which may have caused a dolphin or cat to move so swiftly and how the cat can only imagine ever being stationary and the dolphin may make a splashing sound as it comes out of the cannon... Cannot thank you enough for all you do; saves hours.
Thank you soo much. Your reqources have really helped me this year.
Thank you very much for all the resources!
Another fantastic PPT to help with the teaching of the new A level. You are a real star!
