I think Foundation of 4 Unit is an old edition. Be sure to buy the '2nd edition' if you are going to get one. (Btw there are two different versions of book cover for the 2nd edition, one being older than the other. But as long as it's the '2nd edition,' the contents are exactly the same.)...

No, it's true that Patel is the author of MX2 books for excel series, but there is a separate blue-coloured book by Patel. It was also published by the same publisher (i.e.Pascal Press). It is very thorough but sometimes, like in graphs chapter, it isn't so good.

Board of Studies should fire them and hire state ranking students instead lol.

n!/3!(n-3)!-2(n+1)!/(n-1)!2!=n!/(n-1)! n(n-1)(n-2)/3!-2(n+1)n/2!=n (n-1)(n-2)/3!-2(n+1)/2!=1 n^2-3n+2-6(n+1)=6 n^2-9n-10=0 (n-10)(n+1)=0 n=10 or -1 Edit:Whoops, n can't be -1 Thus, n=10

LOL I don't know the formula for 3-degree ones... Edit: Just discovered by googling 'cubic formula'...

What's the formula?

just tried since I could think of no other ways

I see.... No idea how to do this question then...

LOL.... Anyway, since I'm getting something imaginary, can someone plz correct my working... From my previous post in this thread, tan^3 x+tan x -1=0 Differentiating in terms of x, 3tan^2 x sec^2 x+sec^2 x=0 3tan^2 x=-1 tan^2 x=-1/3 tan x=i/root3 wth... imaginary number...

working??

OH I got it... I'll post it soon (I hope it's correct.) Edit: Whoops. it was wrong... Still can't do it..

Can this question actually be solved?

If anyone can solve.. cos^2 x=tan x 1=tan x sec^2 x 1=tan x (1+tan^2 x) tan^3 x + tan x -1=0 I just can't solve after this..

But the 2 a's are already put in a specific order when the order of koala was fixed, wasn't it? Not sure though..
