Answer 2

Unable to see..
My Office supports only doc file and not docx..

Answer 3

here

Answer 4

are these separate questions?

Answer 5

@precal yes all the questions are seperate

Answer 6

ok the first three are indefinite integrals
but what about the other ones? What are your instructions for those?

Answer 7

See, if you solve first then you can definitely solve other two..

Answer 8

@precal @waterineyes @ash2326 the last question is a differential equation which we have to solve using Integral factor the 4 and 5 th questions are again differential equations and first three are integration by susbtitution you just have find the answers

Answer 9

ok, just helps to post the instructios with your problems.

Answer 10

@precal can you help me these questions have really fried my mind

Answer 11

not sure, what course is this? I would just treat the first three as indefinite integrals

Answer 12

@waterineyes I tried but i cannot :(

Answer 13

Wait dear..

Answer 14

let's see what wolframalpha has to say

Answer 15

Answer 16

My equation editor is not working..

Answer 17

http://www.wolframalpha.com/input/?i=integrate+sinxdx%2F%28sinx-cosx%29
does this help you at all?

Answer 18

are you solving for a in the 4th one?

Answer 19

not sure what to do with the others at this point? It would help to know what course this is, in case I have any books in my library I can go read up on....

Answer 20

@precal 4th one is a differential equation

Answer 21

ok so this is a Differential Equations course? It has been a while since I have studied this, I might not be able to help....

Answer 22

See in case of equations like these:
We make some little substitution:


Numerator = A(derivative of denominator) + B(Denominator)


Till here you got it??

Answer 23

@precal and @waterineyes last three are all differentila equations

Answer 24

@waterineyes yes

Answer 25

Now wait a minute it will take time to write...

Answer 26

I am solving your second question:

\[\int\limits_{}^{}\frac{dx}{1-tanx}\]

Now,

\[tanx = \frac{sinx}{cosx}\]

By putting:

\[\int\limits_{}^{}\frac{cosx}{1-sinx}dx\]

Now we use that substitution:

Numerator = A(derivative of denominator) + B(denominator)

\[cosx = A(\frac{d}{dx}(cosx - sinx)) + B(cosx - sinx)\]

\[cosx = A(-sinx - cosx) + B(cosx - sinx)\]

From here you got or not?

Answer 27

Oh sorry there will be:

\[\int\limits_{}^{}\frac{cosx}{cosx - sinx}dx\]

Answer 28

@waterineyes first three i got i need the help with last one especially i am just so darned confused

Answer 29

@precal I was using wolframlapha to solve the last question but it is not working I am new there can you help me out

Answer 30

close out this problem and do a new post, except ask for help with wolframalpha
I don't really know how to use it, but many people here do.
state "need help with wolfram alpha" in your post, many people will help you.
