in model casio fx-82ms i must do some scientific calculations with logaritm functions but the calculator calculates all problem base of ten(10) but i need base of two.
anyone can help me?
Always remember, you may use the natural logarithm to solve for any base: i.e., for any arbitrary base b, the logarithm of x to the base b is: ln(x)/ln(b)
/Try it!
Convert between bases:

You can convert a log of x in base a to log of x in base b, divide by the log of a in base b.
This could be better answered on the math site, but is easy enough to just answer here.

I'm new to solving big -O and analysis questions and I'm slightly confused on this problem. excuse me if my math is wrong but f(n) <= Cg(n) in this case n(2^n) = f(n) and 2^2n = g(n)
boiling it down I get n/2^n <= C after working it out.
im lost on how to find n0 and C, I assume n0 is 1 as it is usually the case, but im uncertain of C, i assume its 2 but im not sure how to show so.

((A*55)/(A+1815))+4=B
eg.:
((1000*55)/(1000+1815))+4=23.53819
How can i calculate from
23.53819 1000?
A and B are variables.
Sry for my bad english ;)
Thanks any help!
Just follow the steps described before. The goal is to manipulate the expression to get all terms containing the variable to be solved for on one side.
You Have to First do what ever present in Brackets then Division, Multiplication and then Addition and Subtraction.
For any equation you have to follow the sequence.
Hope this helps

I have found this formula for computing Pi value:
But I need to compute only(for example - 1000th) number of Pi value. How I can do it with provided formula?
Thanks.
What you want is called a "spigot algorithm". Take a look at [1] in the section "BBP digit-extraction algorithm for pi". Good luck and have fun.

I've never seen this notation for complexity: Õ(n).
It comes up in the context of learning in stochastic algorithms.
Anyone know this notation? You can't exactly google this...
EDIT: SOLVED
I think people have pointed out the right answer below. In my case Õ() is used to hide an exponential growth of a tree.
It is shorthand for O(g(n) log^k g(n))
Actually, you can google this!
It is a variant of big-O that ignores logarithmic factors. See this wikipedia entry, which I found simply by googling that character and looking at the top entry.

Suppose I have an Arabic character hand-drawn in Thuluth font, as in:
http://arabicletters.info/wp-content/uploads/1.jpg
I was thinking of a way I can recreate the same shape but at a much greater height, whilst leaving the other characteristics intact (stroke width, thickness, the relation of where the curving starts to happen to the height) which then got me curious about a way of finding its mathematical representation and play with it until I can get what I want or any other shape for that matter. Is there a math sub-specialty that can help with this? and for this particular problem, can it be solved using programs like Adobe Illustrator or AutoCAD?
Forgive the noobness.
I don't think deduce is the right word.
You can get what you want if you add sufficient points and do Bezier spline fits to match the letters.
There might be a way to automate the process of adding points, but the "sufficient" criterion is tricky. And then you'd have to tell how to connect points with splines.
Sounds like you're trying to reproduce optical character recognition in Arabic.
