Hahah :P, lool nah they have difficulty pronouncing my name so call me Pie for short
My friend randomly made it up for me at my old school and ended up coming in use! Sometimes if we have a sub teacher and they say my real name people get confused like whos that?

I do love food though....:love:


Lol. I knew a girl who was called Pi too, though this was a nickname because their name was too long o.O

Thats nothing, in my chemistry lesson my teacher put me on the spot asked me to say which type of alcohols each structure was, I didn't have my book on me OR the h/w and just randomly said 'primary etc' and got them all right, my friend was pissing herself with laughter LOOL everyone knew I guessed it all


Got them all right? That's pretty lucky... how many structures were there? :tongue:

The funniest was in my Spanish class at GCSE, the teacher asked my friend sitting next to me to say what 'the head' is in Spanish - he didn't know so I whispered 'la polla' in his ear and he said it :teehee:

Well, that's how it goes :biggrin:
Let's see . . .
Got another problem for you.
If log⁡102=x\log_{10}2=x and log⁡103=y\log_{10}3=y
Express log⁡5(36)\log_5(36) in terms of x and y. :smile:


Can you post hints/solutions for this question please? Thanks :smile:

How about:
I=∫49ln⁡(x−1)x dxI = \displaystyle\int^9_4 \dfrac{\ln(x-1)}{\sqrt{x}} \ dx

I've probably gotten this wrong too
My answer:
[2xln(x−1)−ln(x−1)]49 \left[ 2\sqrt{x}ln(x-1)-ln(x-1) \right]_4^9

I'd have thought the limits gave away a huge clue about the sub...
