What Mr Jackie Lee Says
I love this approach suggested by this student. Do check out how she breaks down the rate of change of y into three components and one of which (the middle one) is modified further via the use of reciprocal rule. This technique was tested in A-level and it is believed to have troubled many candidates. Do ensure you are the other group who survived. 😀
