Can any1 do this integration 4 me?? (1 Viewer)

[Heaven4Angelz]

Can any1 integrate ln(sec x + tan x) dx

Thanx

 

[steverulz55]

pfffft trying to be a smartass

 

[Slidey]

The answer is the integral of ln(sinx+1)-ln(cosx), w.r.t x.

Can any1 integrate ln(sec x + tan x) dx

Thanx

There you have it! Easy as 3.14159265358979323846264338327950288419716939937510.

good thread

that means its not a good thread btw


steph it seems to me that someone has been inspired by your nick>_>

 

[Euler]

This thread reminds me of the integral of sec(x) dx.

 

[CrashOveride]

That's even more complicated, int Sec[x] dx = Ln[Sec[x] + Tan[x]]

 

[Heaven4Angelz]

What?!...i dun get this...there seem to be all sorts of comments on my question?? this is confusing~~~

Refer to my previous post, see attached image.

yeah what a cheater

next they'll ask how to integrate rt (tanx)....though thats do-able

 

[Rorix]

are you sure?


cause i asked dh......

 

[CrashOveride]

It's a bit drawn out yet viable when compared with the initial question asked.

 

[Rorix]

im afraid i was making a bit of an injoke

 

[steverulz55]

are you sure?


cause i asked dh......

hahaha dh yeah wot a noob
he got me and ngai to do it

 

[Heaven4Angelz]

oh well....i didnt know that~~~

Can any1 tell me where can i get the full question and answer to this integration??

 

[steverulz55]

which one? the one you posted or rt (tanx)?

 

[Slidey]

Heaven, to be blunt, you don't WANT the full answer to that integral. I don't think anybody wants it. Leave it be. I'm sure it's content to be alone forever.

That integral isn't exactly 4unit stuff.

 

[Rorix]

yeah its more for the general kids

 

[Heaven4Angelz]

The one i posted....i dont care if it's for general or 4 unit...i just want the full solution....so ...can any1 give me the solution plz~
