    Hi guys, need a little help with a method of differences question if that's okay. The partial fractions gives three terms and I wrote down the expansion (I did this correctly as I checked it against the mark scheme), however I saw no pattern in cancelling out the terms. What is the protocol for going about this when there are three terms instead of 2?

    I have linked the mark scheme's expansion. Attachment 533057

    hey what year was this question?? looks interesting

    thanks

    Can anyone help with a complex number transformation question? I have attempted this and have only seemed to be able to come out with two arg's or get really confused when I start comparing real and imaginary parts. The mark scheme doesn't help too much.

    Tiny hobbit said something about this, apparently the papers were delivered to the wrong place or something by a certain delivery van and they had to issue the replacement papers.

    You don't need to differentiate, you know that sine is a bounded function and takes it's maximum value when sin =1. You can if you want to though, it's just a waste of time.
