PLS HELP FAST

[shut cosmos]

please

help fast

it has a numerical value

[mossy knoll]

A) e^pi•i = -1
B) sin^2x + cos^2x = 1 for all x

Idk how to solve limit tho

[shut cosmos]

can u explain

how

u got -1

[mossy knoll]

Idk the proof, look up “e^pii” on youtube

[shut cosmos]

oh

[weak adder]

It's like e^(π.i)+1 =0

[drowsy forge]

Because e^(ix) = cos(x) + i sin(x). Euler's formula. Ergo, when x = pi, e^(i pi) = cos(pi) + i sin(pi) = -1 + 0i = -1.

[shut cosmos]

so

it is -1?

no matter what?

@drowsy forge

[drowsy forge]

...what do you mean "no matter what"?

[shut cosmos]

what are

how many

[drowsy forge]

There's no "what" to matter, it's a constant.

[shut cosmos]

answers are there

[shut cosmos]

so its -1

right

provided that x is x

[drowsy forge]

...no.

[shut cosmos]

then

whats the ans

[drowsy forge]

Where is x in e^(i pi)?

[shut cosmos]

wait so

whats the answer doe

🤔

[drowsy forge]

...are you telling me that you're working with Euler's identity and you don't even know how variables work???

[shut cosmos]

yeah...

i might've

uh

but

whats the answer

i just wanna know

cuz someone said

theres a numerical answer

to it

[mossy knoll]

A) We can’t give direct answers
B) We’ve already told you that you can’t get help on an exam, stop asking

[shut cosmos]

the exam finished

i just wanna know what the answer is

[drowsy forge]

What's the question?

[shut cosmos]

They just

Gave it

The insert
