Anyone out there enjoy a good number crunch? I'm doing A-level maths and am staring blankly at a piece of paper holding a set of questions i just can't do.

just to see how many of you like / can do maths i'll throw one out and see how it goes....

(maybe your proof will help me understand)

Show that the equation of the tangent to the curve
y=7x^2 - 2e^x at the point where x=2 is
y=(28 - 2e^2)x + 2e^2 - 28.

Cheers for your help....if you can handle it ( evil laugh fading out......)

The answer is 42.

Hope you get the reference tongue.gif

I'd honestly love to help but that looks like someone fell on a keyboard a few times sad.gif.


Hehe... Six times nine? laugh.gif Douglas Adams is my hero.
