Question

could someone please give me an integration problem to solve? (no drawings involved :P)

Answer 1

\[\int\limits_0^1 e^x+2x+100\quad\text dx\]

Answer 2

http://www.scribd.com/doc/33405554/Integration-Practice-Test-1 <---bc I can't do it myself ;p

Answer 3

integrate x^2/4+x^2

Answer 4

\[\int e^{-x^2}dx\]

Answer 5

\[\int\limits \sin^4(4y)\cos^6(4y) dy\]

Answer 6

@amistre64 i think that's unintegrable? :P

Answer 7

@UnkleRhaukus is the answer e + 100?

Answer 8

if \[C _{r}=\left(\begin{matrix}10 \\ r\end{matrix}\right), then \sum_{r=1}^{10}\]\[r.C _{r}\over C _{r-1} \] is

Answer 9

:) its integrable, but you have to do it in another way

Answer 10

how did that become integration @Rohangrr o.O

Answer 11

@lgbasallote almost
\[=e+101\]

Answer 12

it's e + 101 - 1 right?

Answer 13

@Rohangrr: I have no idea why are posting off-topic things in various threads, would you like to enlighten me?

Answer 14

why minus one?

Answer 15

@lgbasallote and @FoolForMath i had doubt on that!! pls help!! :)

Answer 16

[e^1 + 1^2 + 100(1)] - [e^0 + 0^2 + 100(0)]
[e + 1 + 100] - [1 + 0 + 0]
e + 101 - 1
e + 100

Answer 17

@Rohangrr im asking problems myself :P dont ask me of your problems lol..@amistre64 im feeling im getting warm

Answer 18

\[\int\limits{\sqrt{tanx}}dx\]

Answer 19

\[\lim_{n \to\ \infty}\sum_{k=1}^{n} \frac{3}{n}(\frac{3k}{n})^{2}\]
i think i notated it right

Answer 20

lol @amistre64 i reached \(\LARGE \int \frac{ds}{e^{s^2}}\) went in circles after 2 subs

Answer 21

im gonna solve lana's problem

Answer 22

oh your right @lgbasallote
my mistake
very good work

Answer 23

For @amistre64 first problem I would use numerical analysis.

Answer 24

hehe :DDD

aww numerical analysis >.<

Answer 25

For the second one, you form the integration.

Answer 26

that is the integration form

Answer 27

you drive a hard bargain @lalaly -___-

Answer 28

the interval is divided up infinitely; and the function is summed up at all the right end points

Answer 29

no thats not right

Answer 30

Waheed, not quite

Answer 31

could i get a hint on how to integrate \(\int \sqrt{\tan x} dx?\) @lalaly

Answer 32

\[\int sin(x^2)dx\]

Answer 33

lol is that another numerical value thingy amistre :P

Answer 34

;)

Answer 35

the integrations they give you to start with in textbooks is to build your confidence and to get you to believe in the processes; but there are infinitely many integrations that cannot simply be done

Answer 36

that's a nice way to pop my fantasy bubble amistre :P

Answer 37

its a hobby ;)

Answer 38

2/3(cube root (tanx)+lnsecx+c answer of squar

Answer 39

let u^2=tanx

Answer 40

algebraic substitution?

Answer 41

i got \(\Large 2 \int \frac{u^3}{1+u^4} du\)

Answer 42

lol crazy manipulation @lalaly :P

Answer 43

@amistre can u solve the first question gave in here ....

Answer 44

hmmm this thread made me realize...i need to learn how to use partial fractions in integration

Answer 45

hey @lalay can u solve the question u gave here
