# P5 Edexcel Textbook watch

1. First of all, I've got to say I love the new look around here, as you can tell I haven't been on for a long while, but I never thought there'd be this much of a change.

Anyway, I've lost my P5 Edexcel textbook and as yet haven't been able to get a replacement (mainly down to WHSmith taking an eternity to order it) so I was wondering if one kind soul would type up 5, or scan 5 of the questions that I need to do.

The questions begin on page 113 and are numbers 10, 11, 23, 38 and 58. I'd be very much grateful if someone could do this please.

Thanks.
3. I'll do this when I get home if no one has done it by then.
4. i can't b arsed to scan like 5 pages so i'll just type em up for ya
hope u can decypher em hehe

-----------

q10 : intergrate 1 / (sinh X + 2chosh X )

q11 very long induction formula thats impossible to type up

q23a intergrate between 3 and 1 1 / [X^2 -2X +5]^0.5

q23b intergrate between 1 and 0 arsinh X

Q38 (i've changed the symbols for the variables but its the same thing)

given that y=tanX
show that

sin2x = 2y / (1+y^2)

dy/dx = 1 / (1+y^2)

q58a intergrate between 0 and -1 1/ [3-2X-X^2]^0.5

58b intergrate between 0 and -1 X/ [3-2X-X^2]^0.5

man u love intergration mate
