Hi, i was given this question, and i am not sure it is even in the syllabus, as i couldn't find anything in a textbook as an example. i have managed to do part i and ii, but for part three, I ended up with \frac{4}{5}\sqrt {10 + 5\sqrt 3 } instead of the required \frac{4}{5}\sqrt {20 +...

Thank you Integrand, that worked beautifully. You are genius. Thanks integral95, that squaring was really careless of me, didn't even occur to me that it was less than 1, hence that inequality wouldn't hold, was just so desperate to get rid of the square... argghhh. will watch out for that in...
