why b>1? Why not b>0?

should I make it small?

b>1 because the negatitve exponents will take care of values for b between 0 and 1... that make sense?
 one year ago

dpaIncBest ResponseYou've already chosen the best response.0
so it is defined for b>1

maheshmeghwal9Best ResponseYou've already chosen the best response.1
didn't understand ya main concept:(

dpaIncBest ResponseYou've already chosen the best response.0
do you see why b doesn't have to be defined between 0 and 1?
 one year ago

maheshmeghwal9Best ResponseYou've already chosen the best response.1
but what is the problem for 0<b<1.Isn't it defined for exponential f(x) too. Since it also gives a value which is defined as "x". in ur exampledw:1337932045573:dw All r defined:)

there's no problem... with 0<b<1.. it's just not needed...

k! did it have no need due to log?

dpaIncBest ResponseYou've already chosen the best response.0
notice the base of logs CAN have a base between 0 and 1 also but could be transformed and written with a base bigger than 1

is there a reason why this was bumped?

Hi @experimentX I couldn't understand the my basic questiom.Plz help:)

experimentXBest ResponseYou've already chosen the best response.1
I don't understand the reason why b should be greater than 1, but b should always be greater than zero ... for that expression to be defined

maheshmeghwal9Best ResponseYou've already chosen the best response.1
ya I also think this:)

\[ \log_b x = \frac{\log_k x}{\log_k b}\] Also between 01 \( \log_k b < 1\)

I had this problem while studying Logarithmic Differentiation. I think there is some connection between b>1 & Logarithmic Differentiation.
 one year ago

experimentXBest ResponseYou've already chosen the best response.1
\[ \frac{d}{dx} (\log_b x) = \frac{1}{x \ln b}\] At b=1, \( \ln b =0\) is zero ... so it is undefined, so is the above expression, but for (0,1) the expression is defined http://www.wolframalpha.com/input/?i=plot+y+%3D+d%2Fdx+log[0.5%2C+x]+from+0+to+10 http://www.wolframalpha.com/input/?i=plot+y+%3D+log[0.5%2C+x]+from+0+to+10

maheshmeghwal9Best ResponseYou've already chosen the best response.1
So indirectly do u want to say that b>1 is right there! Please tell:)
 one year ago

experimentXBest ResponseYou've already chosen the best response.1
No ... i think i got it wrong it somewhere check this out http://www.wolframalpha.com/input/?i=plot+y+%3D+log[x%2C+2]+from+0+to+10
 one year ago

maheshmeghwal9Best ResponseYou've already chosen the best response.1
k! thanx alot:)
 one year ago

experimentXBest ResponseYou've already chosen the best response.1
it seems i was right ... but somewhat not accurate http://www.wolframalpha.com/input/?i=plot+y+%3D+log[x%2C+5]+from+0+to+2
 one year ago

maheshmeghwal9Best ResponseYou've already chosen the best response.1
K! I understood that.I also think u r right.
 one year ago

experimentXBest ResponseYou've already chosen the best response.1
at b=0, \( \log_b x\) is zero ... and \( dy/dx\) is indeterminate
 one year ago

maheshmeghwal9Best ResponseYou've already chosen the best response.1
ow I have some clues. I will think on that point more. Thanx for clues:)

b cannot be 1 and less than zero ... that's all

maheshmeghwal9Best ResponseYou've already chosen the best response.1
k! but can be (0,1)

maheshmeghwal9Best ResponseYou've already chosen the best response.1
so we again came there; where was our doubt:)

maheshmeghwal9Best ResponseYou've already chosen the best response.1
this is a very confusing state; isn't it?

What should we do now? by the way I have asked this to my sir also online, but they will receive question & give answer after almost a week!!!

what was the original question??

Pardon me what do u want?; that is a video cutted part. I had this problem while studying video:)

Oh ... i thought this is a part of the problem where you got stuck!!

maheshmeghwal9Best ResponseYou've already chosen the best response.1
so is there anyone in OS who can solve our problem:)
 one year ago

maheshmeghwal9Best ResponseYou've already chosen the best response.1
k! np:) Thanx for ur cooperation. When my problem is solved, i'll tell u too.
