The questions are from the partial fractions section to clue you in on how to maybe go about this
The thing is I went further into this, but it got real hectic. The answer I got for the bottom left integral was similar to the answer, but not quite, not sure where I went wrong
I'll give you short answer of tan |dw:1349542124538:dw|
for the other one ... use weistrass subs ... doesn't look nice to me.
Oh.. wow, see i don't have math vision like that wth. how do you even know. just you've done it so many times??
I've seen it couple of times.
that's the right answer for that one, but i have to use the substitutions given, when should I sub them in?
and what is "weistrass subs"
http://en.wikipedia.org/wiki/Weierstrass_substitution no matter what ... these substitutions always work ... if you can find nice answers from other method, don't use this.
looks like you have simplified it so nicely ... |dw:1349542787800:dw|
what hapens to the 4?
i tried taking the 4 out so its 15/256 or something then doing the arctan thing
Buhaha, you took a picture of your notebook XD Nice handwriting at least c:
yeah that would even make it nicer. |dw:1349542995485:dw|
roflmao "nice", yes.
thnx zep, it's easier for you guys to see and understand the problem that way roflmao
It's bubbly like comic sans, and it's legible XD hehe
is that right ex?
should be similar to it. not sure ... try working on paper ... doing here is like playing around. i never get it right.
1/(15/256) arctan [(u+1/8)/(sqrt (15/256))]
a^2 = 15/256 so a is sqrt(15/256) right
i g2g now, but thanks for all your help. if anyone leaves more detailed info that'd be great, i'll be back to check.
and screw weierstrass
I don't like Weierstrass either
