Question

if i have e^(y-b) can i write that as e^y+e^-c

Answer 1

no, but you can write it as \[\Large \frac{e^{y}}{e^{b}}\]

Answer 2

can you help me linearze this in a and b:

y=c+ln((x/a)+(b/x)+5)

Answer 3

i tried taking exp of both sides but i get stuck

Answer 4

hmm not sure what you mean by linearize

do you mean find a linear approximation?

Answer 5

i mean just, make it so that a and b are both linear, if that makes any sense

Answer 6

not really, sry

I'm thinking that you're trying to find a linear approximation at a certain point, but I'm not sure

Answer 7

eg: find a taylor polynomial (of degree 1)

Answer 8

well one example that we had was this
