Can some one help me with this?

My teacher didn't teach us about this and she just gave us this. How do I answer it? Is there a pattern? How do it memories it all?

[late gull]

im extremely doubtful they would make you memorise that, i have forsaken statistics (physics notwithstanding) but its something you reference

[fair parrot]

nope, there is no pattern, you don't have to memorize this

it's just a lookup table

[rose sierra]

My teacher said that i need to memories this or I'm cooked

[late gull]

I dont buy it

[fair parrot]

they're full of shit

[late gull]

no one in any region of academics would ever expect that from anyone

[rose sierra]

Yeah I don't know how but what do I thought with this?

[fair parrot]

in case you're curious, this is a lookup table for the erf() function

[rose sierra]

Okie thank you

[fair parrot]

which is just measuring the area of the normal distribution

it's a useful function in statistics because normal distributions are everywhere

and turns out, there is no analytical formula for the erf() function in terms of x

so the best we can do is just calculate erf() for a bunch of values of x, and just refer to the table whenever we have a normal distribution

which is exactly what that sheet is for

[restive magnet]

I didnt know erf took in complex values

[fair parrot]

oh yeah, the normal distribution is just the real slice of a complex function

but for all intents and purposes you shouldn't need to know that

[rose sierra]

We don't know like the entire class has no clue what to do with it because the teacher only said to memories it and look for patter for the upcoming test

[fair parrot]

that's fucking insane

[late gull]

who on earth is this teacher

theyve lost the plot completely

[restive magnet]

not really
