##p## is probability of loosing

I am trying to estimate probability of loosing (probability of bankrupt ##Pb##) using Martingale system in betting. I will ilustrate my problem on the following example: Let: ##p## = probability of NOT getting a draw (in some match) We will use following system for betting: 1) We will bet only...

The units of T are [N/m]. It means it is a force per unit length (Newtons/metres). unit of h is meter [m] and the units of rho are [kg/m^3].

Hello, natural frequencies of (circular) membrane are expressed in every textbook as: where is the m-th positive root of the Bessel Function of the first kind of order n. For m=1, n=0: ξmn = 2,405. represents the radius of membrane, and is the velocity of wave propagation...

Yes. Exactly

I am modelling eardrum. Simplified eardrum

I am trying to anallytically determine natural frequencies ƒ of the tympanic membrane. I am using 2D sectorial annulus membrane as a simplified model of tympanic membrane according to following picture The parameters that i want to use are following: THICKNESS = 0,1 mm The natural...

I understand. A good way is to use ezplot as well for a rough estimation of points, where functions is zero (intersection with x axis) and then use this rough guess as x0 input in fzero for precise value

Yes. I misused fzero function. now it works for me aswell!function ffu = f(x) ffu = besselj(0,0.5*x)*bessely(0,4.5*x) - besselj(0,4.5*x)*bessely(0,0.5*x); and fzero fun=@f x0=2; S=fzero(fun,x0) will find solution. It finds only one solution which is close to the x0 value but its not the problem.

Hello, i am trying to solve this equation for x besselj(0,0.5*x)*bessely(0,4.5*x)-besselj(0,4.5*x)*bessely(0,0.5*x) ==0; I tried vpasolve, but it gave me answer x=0 only. fzero function didnt work, too. What function can solve this equation? Thanks

Well i think i can export WORD into PDF and overcome this problem?

Hello, i use mathtype 7.3 in word - in office 365 for equations. Everything is okay, but when inserting an inline equation, an extra space is inserted after the equation in Word. It looks ugly. i found http://dessci.com/en/support/mathtype/tsn/tsn143.htm but it didnt help me. It does not work...

I am writing my PhD Thesis now and i have a lot of equations. I use Word (for text) and for eqations i use MathType. For text i use Calibri font 12pt but for eqations - in MathType i prefer Euclid. It looks pretty good but i would like to ask you, if it is a problem that fonts for texts and...

Yes, i kindly appreciate your help sir. now i understand it much better. I just don't know why books don't use ,,your,, derivation.

Well here is MIT professor talking about this problem. At 18min. he is talking about phase angle. However it is same as my solution... In comment section u can see one person asks same question as me ( Huihuang LaiPred 1 year ago Sir, at 18:28 how can delta be equal to pi? Isn't delta an...
