DBAHO Posted December 1, 2003 Share Posted December 1, 2003 Definitely Heather for sure, but what's da prob u got with logs? Quote Link to comment Share on other sites More sharing options...
SuperSteve Posted December 1, 2003 Author Share Posted December 1, 2003 Yeah, I know Heather is a teacher and all, but she ain't around. I need help with stuff like this, but ya can't use a calculator (answers can contain logs it says): Quote Link to comment Share on other sites More sharing options...
Heads22 Posted December 1, 2003 Share Posted December 1, 2003 Yeah, I know Heather is a teacher and all, but she ain't around. I need help with stuff like this, but ya can't use a calculator (answers can contain logs it says): Sorry man, I think that's our next chapter in Analysis. I can bore you to death with inverse trig functions though: cos^-1(cos(3/5)) ...that's an easy one. Right now we are covering periods and sinusodial waves.

AssHatSoxFan Posted December 1, 2003 Share Posted December 1, 2003 well logs are base 10 so you can take 10^(log (log(x-15))=10^0 and for the other problem sum of logs is same as multiplication inside so log (2x-9) + log (3x-1) = log ((2x-9)(3x-1)) i hope this helps and is correct Quote Link to comment Share on other sites More sharing options...

sox4lifeinPA Posted December 1, 2003 Share Posted December 1, 2003 damn...I haven't taken a math course since my freshman year of college. I'm much happier with social sciences.

Chisoxfn Posted December 1, 2003 Share Posted December 1, 2003 I need help with logs. Anyone good at math who can help me? I'm pretty good at math. Log's are calculus right? I may not remember all of it but I did pretty decent in the class. Whats the specific question? Quote Link to comment Share on other sites More sharing options...
Chisoxfn Posted December 1, 2003 Share Posted December 1, 2003 Yeah, I know Heather is a teacher and all, but she ain't around. I need help with stuff like this, but ya can't use a calculator (answers can contain logs it says): What your gonna want to do is clear the log log in the first part. I have no idea what log times log is but I'm assuming thats somewhere in your book (I only remember the processes, everything else is very fuzzy). That may work out to an even number and then you'd just do the x-15 to work it to zero. In this instance I think x just has to be 15.

Chisoxfn Posted December 1, 2003 Share Posted December 1, 2003 Ah crap...if I had an example problem with the solution I could do more, but now I'm confusing my self, lol. I should know this, but alas, how quickly I forget what i learn. Quote Link to comment Share on other sites More sharing options...
DBAHO Posted December 1, 2003 Share Posted December 1, 2003 Just do log 10 so it cancels out to 1, and then find x from the brackets. Quote Link to comment Share on other sites More sharing options...
Be Good Posted December 1, 2003 Share Posted December 1, 2003 I hate math infact the only way for me to have a %10 chance of passing is to do every HW since my test avg is 30 Quote Link to comment Share on other sites More sharing options...
