x'=1, f(x) = e^(x^2), n=4, then you just use the formula

mathematically right using the common definition of the function erf, though I didnt read so I didnt do the simpson thing

2023-03-05 23:11

2 replies

no, erf is defined for exp(-x^2), this here is exp(+x^2)

It's easy. Just google simpson's method and put in the numbers.

Formulae are for noobs. Real men use the derivation :>

i got 5 cancers when i saw that equation

2023-03-05 23:11

Is this high school level or uni? You just plugs the number to the formula, as long as you know, you can solve it

2023-03-05 23:17

Not doing your homework wtf

2023-03-05 23:18

Imagine actually having a desire to study something like this, I will never get you people

its ok

= 1/3*0.4 * [ f(0.4) + 4f(0.8) + 2f(1.2) + 4f(1.6) + f(2) ] = 15.417 might have made some mistake though

okay I ran it again slowly on my calculator and now I'm getting 16.47. Real integral value is 16.03 according to wolfram, close enough!

in math "close enough" doesnt exist you either do it right or you did it wrong

bro... this is an approximation formula. We can't integrate e^x^2, even computers have to use approximation methods in this case. If we need more precision, we can always increase the n of intervals, but it was asked for us to do it with 4
