Page1/1            Infinite Logarithmic Series 2011-08-08 From Sourik:Dear Expert, In my Amithabha Mitra and Shambhunath Ganguly's "A Text Book of Mathematics" I found the formula of log (1+x) where the base is e and x lies in between -1 and +1.As I want to learn Mathematics,I am not satisfied with the mere statement of the formula.Please help giving me the full proof. Thanking you, SourikAnswered by Robert Dawson.     A logarithmic equation 2010-09-08 From Rohit:x^2 + k*ln(x) - c - k = 0 Where k and c are constants.Answered by Penny Nom.     Understanding log equations 2007-05-10 From Sean:The number, N, of people who have heard a rumor spread by mass media at time, t, in days is modelled by N (t) = a / 1+ be^ -kt. If 50 people have heard the rumour initially and 300,000 people hear the rumour eventually, find a and b. If the rumour is initially spreading at the rate of 500 people per day, find k.Answered by Penny Nom.     Differentiation, powers and logs 2006-01-06 From Claudia:Question: how do I find the derivative of x* ln(x+(e^2))^2 x^lnx x^(e^(-x^2)) Answered by Penny Nom.     Logarithmic differentiation 2005-05-23 From Richard:I need to convince myself that I understand the process of differentiating y=xx. The specific question is that if I have to take the logarithm of both sides of the equation how can differentiate the following? y= {(x+2)(x+2)}/{(x+1)(x+1)} - {(x+1)(x+1)}/(xx), I have an idea that the differential of this fairly complex function is itself ... am I right or wrong.Answered by Penny Nom.
