First one is probably a classic, second one is very easy
second one is already done ... under 60 seconds

I'm sorry, not hard enough?

the first one is definitely very long and messy

the last one very easy

You like applied maths, surely long and messy is what keeps you going? I've got the answers anyway, and I agreed with them when I did it.

Tomorrow I'll pick out the nice, tough, elegant ones, but atm its at random

I see ...

Hopefully some of the big boys here will come and help me when I get stuck ...
(my integration is not what is used to be)
6. Anyone willing to help with a probabilities question ?

I might be able to (in general less likely if it is a counting-type question)

Have you attempted the first one? If so, how did you go about it? I did it by parts then resolved into partial fractions. Its getting it into a more 'friendly' form that isn't obvious...

Sorry I have not attempted any of them as I am going through one of my busiest spells.

Haven't done it yet but Yh parts on 1 and arccot(etc) with u=arccot will most likely work, you can use the relation between arccot and arctan which might make it simpler but I'm not too sure without doing it.

I was wondering whether the arccot X +/- arccot Y formulae may help... I haven't tried this yet, however.
