Question

Anyone familiar with mathematica?

Answer 1

http://www.math.ysu.edu/~faires/Numerical-Analysis/Programs/programs/mathematica/ I need help with ALG023.MA
I evaluated the notebook

Answer 2

and I entered the function
\( \large e^{6x}+3(ln2)^2e^{2x}-(ln8)e^{4x}-(ln2)^3 \)

Answer 3

Like I am not sure how to enter this function

Answer 4

hmmmmmmmm

Answer 5

@nincompoop r u there?

Answer 6

ohhhhhhh Ill try to input that

Answer 7

This is how your input should be in formal Mathematica notation:
Exp[6x]+3 Log[2]^2 Exp[2x]- Log[8] Exp[4x]- Log[2]^3

Answer 8

hmmmm not sure gotta play around a lil
Thanks guys :)

Answer 9

@experimentX Can u help me out?

Answer 10

like I think smth is wrong since I think its taking too long to converge

Answer 11

So maybe I am inputting it incorrectly

Answer 12

this right?
http://www.wolframalpha.com/input/?i=e^ {6x}%2B3%28ln2%29^2e^{2x}-%28ln8%29e^{4x}-%28ln2%29^3

do you know WA interprets latex?

Answer 13

nooooooooooooooooooo

Answer 14

lol ... probably you should remove { }
E^(6 x) + 3 Log[2]^2 E^(2 x) - Log[8] E^(4 x) - Log[2]^3

Answer 15

ok let me tryyyyy

Answer 16

for these types ... create a W|A accound (free one) ... sometimes it let's you copy things around ... like Mathematica input

Answer 17

ohhhhhhhh i willll

Answer 18

smth is going wrong with my mathematica ughhhh

Answer 19

idk smth is weird
a number my book got for the 6th itteration I got for the 16th iteration

Answer 20

so either I am entering smth incorrectly orrrrrrrrrrr there is some typo

Answer 21

how did u get that?

Answer 22

Like how can i do that input output thingy?

Answer 23

copy paste .. lol

Answer 24

Like u see I got for 16 --> -0.182888 and the book got this number for the 6th iteration
So I kinda have a sneaky feeling that somehow the program is messing up

Answer 25

Newtons method involves dividing the function by its derivative so I wonder if the derivative is getting messed up

Answer 26

when it comes to programming mathematica ... i at zero level. If it were Matlab ... i could have re- programmed it

Answer 27

try this
Log[4] == Log[2]^2

Answer 28

So like how wold u get it to be (log[2])^2?

Answer 29

Where should i try that?

Answer 30

try to create a new notebook ..

Answer 31

ohhhhh

Answer 32

It said false

Answer 33

lol I dont know a thing from beanssss

Answer 34

Just followed what u told me to do idkkkkkkkkkkkkkkkkkkkkkkk

Answer 35

lol whadya mean?

Answer 36

I am confuzzleddddd

Answer 37

When I enter Log[2]^2 does mathematica read it as Log[4]?

Answer 38

Or does it read it as (log(2))^2?

Answer 39

this means
Log[2]^2 not equal to Log[4]

Answer 40

YAYYYYYYYYYY

Answer 41

Ok maybe there is a typo in my book whtvr

Answer 42

I am totally driving u guys crazyyyyyy

Answer 43

you should learn programming
http://www.mathprogramming-intro.org/
google them, there are lot's of stuff ... I'm learning after exams

Answer 44

ikkk I should. I just dont know where to begin

Answer 45

Ill bookmark this page

Answer 46

I just never have time in my life idkkkkkkkkkkk
I think i gotta start organizing my life

Answer 47

haha ... you should learn from how to evaluate expression ... probably

Answer 48

Probabbbbllyyyyy

Answer 49

hahah the only time I learnt about programming was back in HS we learnt visual basics hahahah which isnt relevant

Answer 50

no one works with VB these days. I tried to do a VB in second year. it was a failure. I don't know why everyone is interested in python these days.

Answer 51

idk It seems like C++ is what everyone studies idk

Answer 52

i learned C on undergrad school ... tried to learn c++ ... didn't complete it.

Answer 53

i thin i'll try to learn python/mathematica/matlab ... after exam

Answer 54

hahahah ure always learning after exams

Answer 55

idk I am getting sick of studying. Nothings interesting nemore. idk The course I am taking right now is soooooo boring. idk Like after a while u just get sick of everything

Answer 56

probably you skipped the basics ... mathematics always seemed interesting. my teachers were awful ... didn't understand algebra well. I failed in finals of my final year.

Answer 57

idk Its numerical methods and I get headaches when like computing with tiny numbers. I keep on having to check if I am made a mistake. I guess I am not cut out for math :(

Answer 58

yeah ... i don't like it either ... Maybe i failed the day before yesterday's exam because of it.
seeing it I thought it could ... but due to lack of practice i couldn't do it.

Answer 59

U recently took that course toooo????

Answer 60

I have it in my course ... Mathematical physics.

Answer 61

ohhhhhhhhhhhhhhhhhhhhhh its very technical and I so hate it. maybe it will get a lil bit nore exciting. Its like its a no brainer once u know the formulas u just enter all the info

Answer 62

well ... i still love deriving the Euler's method and Newton's Rhapson's method ...
I hate RK-4 ,,,,

Answer 63

didnt get up to RK-4 yet

Answer 64

Are u familiar with aitken's method?

Answer 65

the picture looks beautiful
http://upload.wikimedia.org/wikipedia/commons/thumb/e/e0/NewtonIteration_Ani.gif/300px-NewtonIteration_Ani.gif

Answer 66

Ohhhhh i lovee thattttt

Answer 67

probably not ... i skipped the whole chapter. all i studied for exam was RK-4 and Newton interpolation ... lol ...i couldn't do both.

Answer 68

lol ya well i dont have to take exams I just have to hand in work So i dont have to memorize any formulas

Answer 69

very nice for you ... you don't want to be in my position right now.

Answer 70

No i reallyyyyyy dont lol

Answer 71

my stat
1 down -- flunked
3 remaining --- gonna drop probably

Answer 72

Cuz u r taking wayyy too many courses at once

Answer 73

this year I'm dead :(((

Answer 74

probably i should quit physics and start math ... lol

Answer 75

lol but ure finished with ur undergrad?
Like I kinda find it crazy that ppl study for sooooo long

Answer 76

yeah ... i graduated with physics, and half way through grad school ... tried to get extra math in undergrad .. failed on both.

Answer 77

Once u graduate then what?

Answer 78

dunno ... it's just so nice to be freeloader at home being student.

Answer 79

lol hahahahah i guesssss

Answer 80
