What does A approach as t gets bigger and bigger

[vagrant kindle]

not sure

i put in a super large number for t

and get math error on my calc

[nimble gazelle]

When t is really big the +1 on the denominator doesn’t really change it

So it’s more like 1200e/400e

And the e’s cancel so the max would be 300

[vagrant kindle]

why does the +1 not change

yeha the mark scheme gets 300 aswell so ur right

but i dont get y the +1 doesnt change

[nimble gazelle]

Dyk about finding horizontal asymptotes

[vagrant kindle]

ermm

yea

isnt

it y=0

for a normal graph?

[nimble gazelle]

If the graph is 1200x/(400x + 1)

When you find the asymptote u jus divide the coefficients of x

[vagrant kindle]

oh ok

so 300x/1?

[nimble gazelle]

Say t was inifinitely large, then +1 would have no effect

[vagrant kindle]

hmm fairs fairsss

so what if it

was +2 instead of +1

would it still have no effect>

?

[nimble gazelle]

Doesn’t matter + what

Like the difference between a trillion and a trillion + 5 is tiny

[vagrant kindle]

ohhhk that makes more sense now

so the numbers are alr too big

as t tends to infinite

[nimble gazelle]

Ye

And then the e cancels

[vagrant kindle]

you disregard the + or - numbers

as they would b negigible

[nimble gazelle]

Basically ye

[vagrant kindle]

yeahhh fair enoughhh

nice one bro

that makes sense

appreciate it
