Integral Maths Answers !!link!! -

I'm currently using Integral Maths for my A-Level (MEI spec) and I'm stuck on a few topics (especially the "Large Data Set" questions and some of the harder integration by substitution problems).

Alternatively, if you're a teacher – why do you keep the worked solutions hidden? It feels like we're being forced to guess rather than learn. integral maths answers

Thanks in advance.
