2000 - Q3(c) (1 Viewer)

[speed2]

hey guys, i can't get Q3(c) in the 2000 paper, i got up to the last step as shown in the answers in MANSW, but the last part involves using the calculator and when i enter what they have got as the last step i get a MATH ERROR, i think because the numbers are outside the calculators range.

could nebody please help me with this?

yeh, well when you expand it, on the top you should get something with a 100^(100+1/2)
over 10^12 x60x60x24x365.25
so on the top
its something (2pi)^.5xe^(-100)x10^2(100.5) / 10^12x 6^2 x 10^2X365.25

so you end up with the numbers on the top and button, and you have 10^201 / 10^14
times by the rest of the numbers, then you put them into your calculator and times it by that...

i hope that helps, i know my explanation is pretty dodgy

but when u put 10^201 / 10^14 into the calculator it comes up saying Math Error

EDIT: stupid me! just realised that it says in scientific notation.

I'd be intereted in seeing how you would write the anwer without scientific notation .

you would need a whole page to write the zeroes
