Math Is Fun Forum

hiiiiii JaneFairfax ,,,

thank thank thank you very much

you are really intelligent

but can you explain to me the first part    I understand the second part of integration

but why you take the limit   
we know that the integration at zero is undefined..

maybe the question is strange  but I would like to know the exact meaning...

thanks again

yes the final solution , in my opinion, 1/4

you need to use integration by parts

then use substitution with (x+1)=u   in second term of integral   ( du*v)

if you don't understand yet

i can help you more

tell me my brother if you get

first simplify this expression

by usining division by -1 you will find f(x) = 0
thats means -1 is the first zero

you will get

divide by -1 again

and you can complete the answer

hii all..

my solution

apply

we get

then simplify

apply

we'll get

finally

First we use synthetic division..

then we also use the same mathod with another number  -2
to solve

now we can factor

the solution set (3.-2.-1.4)

Toast

yes ,
I drew that's in paint,,
it was hard work,,:|

because I didn't knew anything about topic
:)

thank you very much,,

hiii
unique

good work..

but there is a mistake..

see to my solution

hmmmmmmmmmm,,

What multipied by 2^x-1 equals 2^3x-2 ?.

(2^x-1)(2^2x-1)=2^3x-2

2(2^x-1)^3=2^3x-2

= 2y^3

Is that a correct answer ?

Answer,,

1.       i

2.       -i

3.       i^o=  1

4.       i^19 = i^3    =    -i

5.       1

6.       1 - i

7.        i^18 + i^13  =  i^2 + i^1    =   -1 +i

8.        1

9.         i - 1

10.        i^29 + i^14 =    i^1 + i^2 =      -i

11.         i^23 = i^3     = -i

12.         1

13.          i + 1

14.           1

15.            1

16.            -1

17.             0

18.            1
