Question

integration by simpson method: b=2 , a=0; n=10
√ x+3 dx

Answer 1

ok well basically what is the simpson rule?
its deltax/3(f1+4f2+2f1...+fn)

Answer 2

delta x= (b-a)/n
can u do it or do you want an answer?

Answer 3

btw is it sqrtx + 3 or sqrt(x+3)?

Answer 4

i just needed to know, how I resolve for the sq root

Answer 5

what do u mean? u use sqrtx+3 for each point

Answer 6

u want 10 sub intervals of 0 to 2
so ur gonna go 0, 0.2, 04, .... 2 just plug into the formula :)

Answer 7

1.st. thank u very much. and been very honest, i get confuse with integration, i just cant see the logic in resolving ecuations that u just make substitutions in numbers and u add some others ecuations but you dont resolve the original one. "well , thats how i see integration" maybe that means that i dont like them or i just cant understand them.

Answer 8

but either way i'm very grateful for ur help

Answer 9

LOL its aight :P
all u have to do is calculate ur delta x divide it by 3
and then u need 10 intervals and u plug into the formula :) dw just stay calm its not too hard :)

Answer 10

ok!!! I'm gonna cook something and then i'll keep working with these integrals. thanks

Answer 11

hahaha sure :P

Answer 12

food always helps :P

Answer 13

ill find out very soon its that true

Answer 14

if i want to resolve the same equation with the trapeze rule' woul be the same but with n=2 and then 2()+2()+2()...?
