Logarithmic UISlider 
Category : Development Tools & Services 
Are there any preferred methods for having a UISliders values change
logarithmically, rather than linearly? So that, for example, the value
changes from 0 to 25 over the first half of the slider, and 25 to 100 over
the second half.

How to Calculate Logarithmic Mean 
Category : Hobbies, Games & Toys 
Almost everyone is familiar with the mathematical concept of a mean, even
if they know it by its more common name, the average. By summing the terms
in a series and dividing the resulting number, you can obtain the mean of a
given group of numbers. A logarithmic mean is very much like this. Often
used when calculating temperature differences, a logarithmic mean is
obtained in much the same way as

How to Do a Logarithmic Graph 
Category : Hobbies, Games & Toys 
Plotting a logarithmic graph is similar to graphing any other mathematical
function. A logarithmic point consists of both an independent variable,
which is the inputted value, and a dependent variable, which is the result
of the log. Knowing the shape of the graph of the general log function
allows you to perform transformations on it such as vertical and horizontal
shifts, shrinks and stretches a

How to Make a Logarithmic Graph 
Category : Education 
Logarithmic functions are the inverse of exponential functions. Thus,
making a logarithmic graph entails performing the same steps that one would
use to make an exponential graph. Unfortunately, both exponential and
logarithmic functions do not offer a magic formula that can be used to plot
points. The only way to make a logarithmic graph is by using arbitrary
values of "x" to solve for the logari

How to Calculate Logarithmic Decibels 
Category : Hobbies, Games & Toys 
Decibels, denoted as "dB," are units measuring the intensity of sound. This
unit is commonly used in acoustics to quantify sound levels. Decibels are
the logarithm of the ratio of the sound (I) to the threshold of hearing
(Io); decibels= 10 x log10 (I/Io). The standard threshold of hearing is
10^12 watts / square meter. Use a calculator to compute
decibels.Difficulty:EasyInstructions Things Yo

How to Use the TI83 to Graph Logarithmic Function 
Category : Education 
Logarithms are one of the more difficult types of functions to graph by
hand, making a graphing calculator an appealing option. However, many
logarithmic functions are also tricky to graph on the TI83. This stems
from the fact that the calculator can only calculate logs with two kind of
bases, base 10 and base e (expressed as ln). Logs often have other bases
(e.g., 7, 5 or 2). Some of these logs,

How to Calculate Logarithmic Expression 
Category : Education 
Logarithms may be thought of as the opposites of exponents, just like
subtraction is the opposite of addition. An exponent may be described as a
number raised to a power. Calculating or solving a logarithmic equation
requires a basic understanding of arithmetic and algebra. One way to think
of logarithms, where ^ means "raised to," is that y = b^x is the equivalent
of log (base b)(y) = x.Difficul

Logarithmic plotting of points 
Category : Development Tools & Services 
I was wondering if give a number of 2D points, how do calculate where to
draw a point on a screen in a logarithmic y scale? I tried to
just take the logarithm of all the yvalues of points and than plot them
'normally' (plot point [x, log(y)] => on height: height*log(y)/log(max)).
But this approach causes problems for yvalues under 1. So this makes me
wonder if my method in general

Logarithmic series of numbers from 1 to MAX 
Category : Programming Languages 
I'd like to calculate a logarithmic range of numbers from 1 to MAX, with
the approximate total count of numbers being TOTAL. A
nonlogarithmic example might be: $max = 3600; $total =
100; $range = array(); for($i = $total; $i > 0; $i){
$range[] = round($max/$i); }
This creates a
roughly equally distributed range ho
