Question

LGBAINTEGRAL:

\[\huge \int (2x^3+5)^4 dx\]
is this integrable??

Answer 1

i dont think i want this im changing the question lol

Answer 2

Hi lgbasallote :)

How are you?

Answer 3

Do you know which function is integrable or which is not? Do you know?

Answer 4

there i think that's better

Answer 5

i dont think that last one could be solveable by simple techniques

Answer 6

Use binomial and expand it, if you can

Answer 7

wont integration by parts work?

Answer 8

It is integrable dear.

Answer 9

And this is totally Integrable.

Answer 10

@vishweshshrimali5 may help u

Answer 11

Don't use by parts. Choose an easy way.

Answer 12

I agree with Ishaan94

Answer 13

what easier way? expansion?

Answer 14

yes. Expand.

Answer 15

hmmm...

Answer 16

yeah i guess if it's just expansion then i can do the rest from there

Answer 17

and seriously...
\[\int \frac{x}{2+\tan x}dx\]
that's integrable??? hahaha

Answer 18

yes this is integrable

Answer 19

By Parts, perhaps

Answer 20

If there would be 1 in the numerator then it can be integrated bu there is x..
Ha ha ha..

Answer 21

lol wow

Answer 22

i dont wanna attempt it o.O

Answer 23

My answer is for ur original question

Answer 24

:yeah i know haha

Answer 25

@lgbasallote

Very true

Answer 26

I think it is not integrable dear.

Answer 27

This function is not integrable.

Answer 28

for ur next question

I don't have any idea for this but this is what wolfram says

Answer 29

I just lost my work. I can only think of by parts. I haven't tried any calculator, so I don't know if its integral is defined.

Answer 30

but wait for Ishaan sir

may be he would have a better way to solve

Answer 31

So this is not integrable. Right?

Answer 32

perhaps not

Answer 33

Not perhaps. It is ofcourse not.

Answer 34

yes it is not integrable

Answer 35

\[ \int \sin x /x dx\] is not integrable ... somehow this integration seems same type.
