What's that angled bracket on top of n? In my copy of "Higher Algebra" by Hall & Knight,(1955 Ed; 1st Edition 1887) there is something similar but the angled bracket appears on the lower left - this was the old notation for n!
Thanks for the help guys I realised my errors and can do it/understand it now. Thanks heaps! I'd upload the solution but I don't know how to put the actuarial angle in the bos LaTeX editor only on the LaTeX editor on my computer. That and you guys would find it very boring
No this is financial maths for actuaries. In saying that, you will encounter some of it like interest rates compounded continuously or momently etc. I just think the treatment of the material is a little different. I'll let you know though
