<Kasadkad> tan(x) is not a hard thing to integrate, it doesn't take anything more than substitution
<jerware> hiu
<adamjon858> If you really cared...
<jerware> hi
<adamjon858> heh
<adamjon858> does anyone happen to have a solutions manual to that book
<EdBoy> Kasadkad: ...wait
<adamjon858> I don't want help on homework or anything...I'm just doing a chapter review for my own good
<EdBoy> I thought it was ln(|cos x|)
<EdBoy> -ln*
<DemisM> if i have a number k how can I find out the first number in the highest spot say i have 3457 how can I get 3 then 4 then 5 then 7? I can get it in the reverse order using division algorithm or mod.
<adamjon858> The answers are in the back...but it doesn't show you how to do the problems
<EdBoy> or is that the derivative
<adamjon858> I'd really like a solutions page for the chapter 6 review.....Just putting it out there
<cyclicFifths> EdBoy: it is also -ln(|cos x|) = ln(|sec(x)|)
<EdBoy> Cool
<jerware> i have a negation question. it puzzles me since it's in english terms. if i dont sleep, then work is hard. there fore p: i dont sleep q: work is hard right?
<slava> yeah
<jerware> p -> q
<slava> sec x = 1/cos x
<cyclicFifths> yup
<jerware> and the negation of p -> q is p and notq
<jerware> so will the english equivlant remove the 'if' and 'then' ?
<jerware> and use and?
<jerware> being... i dont sleep and work is hard
<jerware> correct?
<EdBoy> that's bull
<EdBoy> I sleep plenty and work is still hard.
<cyclicFifths> ~(if p then q) = if ~p then ~q
<jerware> what if i cant have a negation in a compund statment
<jerware> cyclicFifths i want the english equivilance
<cyclicFifths> if i sleep, then work isn't hard
<jerware> what about the and ?
<cyclicFifths> what do you mean?
<jerware> thats not a negation. that just saying the same thing indirectly
<cyclicFifths> i'm sorry, what is it saying indirectly?
<exculpate> what is meant by writing sin(13pi/6) in terms of x where x is 0 <= x <= pi/2
<jerware> the negation of the truth tables for p -> q is p and not q
<exculpate> ?
<cyclicFifths> so if p then not q
<cyclicFifths> so if i don't sleep, then work is not hard
<jerware> makes sence
<jerware> wait
<jerware> what about logical and
<DemisM> is there any algorithm that would yield the highest order number in say 345 would give me 3?
<jerware> p ^ !q
<cyclicFifths> it's pretty much the same i believe
<jerware> ok
<jerware> cyclicFifths out of curiosity, are you familiar with truth tables?
<jerware> and discrete math?
