Mhm, there is. I think it's about 3-4 lines of working? I remember I was panicking in my mock exam, I can't fathom how I actually received the answer from my method. I guess just analytical thinking. Haha. I can't post part a) for some reason though at the moment.

Thanks I will take some time to digest that information, and see if I understand it! I probably will
Do not worry about it. If you're a GCSE student, then you'll NEVER meet that. If you're an Additional Maths student; you may, however it is highly unlikely. It is deemed to be difficult, unless you follow the stringent method for success. Whatever you're studying for, good luck!
