Is this the same as regular sequencing?

it's asking for the equilibrium values so you need to set a_n+1 = a_n and solve for a

Vocaloid:

so for a) a_n+1 = 2a_n*e^(a_n) becomes a = 2a*e^a and solve for a

zarkam21:

end up with 2?

zarkam21:

e^2?

zarkam21:

:S

Vocaloid:

hm, not quite, we just need to consider a = 0 makes both sides equal to 0 so 0 is the equilibrium value

zarkam21:

is that in every case?

zarkam21:

like does a=0 in every problem

Vocaloid:

no, you need to consider them on a case-by-case basis

zarkam21:

so which value makes sense in the formula

Vocaloid:

yes, you need to solve for the a-value that makes a_n = a_n+1

zarkam21:

okay

zarkam21:

so it just needs to equal the given value in a way?

Vocaloid:

you need to take the equation, replace "a_n" and "a_n+1" with "a" and solve for a.

zarkam21:

got it

zarkam21:

is like x3 correct or should it be 3x

Vocaloid:

uh is it supposed to be 3^x in the logarithm or 3x

Vocaloid:

oh

zarkam21:

x3 i think

Vocaloid:

yeah Idk about the second one
