just put it in the web2 calc

Thank you Chris and Alan,

I have finally looked properly at what you are telling me, and hopefully I will remember.

I have always had problems with this because I could never see why it was true and I have a reall problem reproducing things when I don't really understand.

 I did not know that e could be defined that way

I will try and remember.

$$\boxed{e=\displaystyle \lim_{n\rightarrow\infty}\left(1+\frac{1}{n}\right)^n}$$

3t2 + 5t – 7 is divided by t – 5

$$\\f(t)=3t^2+5t-7\\\\
f(+5)=3*25+25-7=93$$

so the remainder will be 93

See if this helps

No happy, it is  

6*10^6

=6*1,000,000

=6,000,000

Yep got it . thanks Chris.

I shall put this site in our Reference Material post.  :))

NO

$$-x^2+6x-9$$  does not equal      $$(x-3)^2$$      

$$\\-x^2+6x-9= -(x^2-6x+9)=-1*(x^2-6x+9) = -1*(x-3)^2\\\\
$the -1 is not squared so$ \\\\
(x-3)^2 \ne -x^2+6x-9$$

remember 

    $$-3^2\ne(-3)^2$$

consider these two sums

$$20+-3^2 = 20-3^2=20-9=11$$

and

$$20+ (-3)^2 = 20++9=29$$

see        $$-3^2\ne(-3)^2$$

I hope that helps :)

I couldn't see how to add the text. 

Thanks Chris,

How do you write in the circles?

Thanks, .... I think.
