hello there captain black,

I feel I'm inching closer to what my tutor wants.

The assignment is about atmospheric pressure using the equation

*p = *Ae to the power of -kh

We were doing second order approximations to find the values of *p* pressure

at different heights (h) from 0m to 10000m at intervals of 1000m using our intercept (A)(109.95) and our gradient k(-.00014),the second order approximation we were using was;

1-kh+kh2/2! but every time I try to use Maclaurins for it,I end up with similar answers or just a constant answer?

I'm tearing my hair out!!

p.s I think e to the power of -kh may be constant (if this is possible)

thanks again..
