He said "be afraid, be very afraid." I wonder what's going to happen when he meet the great Paul Jefferys.


tear off his shirt and having an ultimate fighting match?

alexxxxxxxxxxxxxxxxxxxxxxxx can you come to my room and help me with maths? soon would be good as im meant to be going out in 26 muints.e...


um no :frown: come on MSN!

also, when you said :

a^x = e^lna. x


is that x.e^(ln a) or e^(x ln a) ?????????????


e^(x lna)

demonstration is simple

you know that

(a^b)^c = a^bc ...well you should

and so backwards a^bc = (a^b)^c

so e^(x lna) = (e^lna)^x = a^x

e^(x lna)

demonstration is simple

you know that

(a^b)^c = a^bc ...well you should

and so backwards a^bc = (a^b)^c

so e^(x lna) = (e^lna)^x = a^x

I thought she meant ln(ax)... :redface: ambiguous. Use reverse polish.

I'll leave a hand written proof on your desk.

No wonder why you don't know what A4 is...

What does that suppose to mean?

so lex i have

Y = ae^(t ln b)

so if i ln that, i get ln Y = ln a + t ln b? is that eright?

no, it applies to the ketters in any form, spoken, handwritten, typed, sprayed in 6 foot letters on my ceiling...

ok, net question, how do i sketch a graph of Y = ae^(t ln b) ? of Y against t?

If you want a straight line, you don't plot y against t. You plot LnY against t.
