I'll try to print code and look for unbalanced brackets, but that looks just fine for me. I put symbol & in the end of some problematic lines and that didn't work neither. And in program I get just one mistake and that mistake is syntax one. Program worked just fine with different shape of...

Fortran says to me that I made syntax error here V1=(Kps*(1-ra**2)*(1-cos(6.2831853*y(1))))/(6.2831853**2* (1+ra**2+2*ra* cos(6.2831853*y(1)/2))**2)

Do I made a mistake in writting this formulas. I don't see them. Tnx for your answer. V1=(Kps*(1-ra**2)*(1-cos(6.2831853*y(1))))/(6.2831853**2* (1+ra**2+2*ra* cos(6.2831853*y(1)/2))**2) V2=(Kps*ra*(1-ra**2)*(1-cos(6.2831853*y(1)))*...

Tnx. That was mistake.

I'm new in programing. Does enybody knows why this don't work. implicit none integer i,N,Ntot,istag real*8 t,U,tpin,k,eg,mstag real*8 rho,Umstag,Urho real*8 eaf,eaftot,lambdaminus write(6,*) 'N,Ntot,t,U' read (5,*) N,Ntot,t,U write(36,*) Ntot/2+1 tpin=8.d0*datan(1.do)/dfloat(N)...

Look at a simple single - component system. And PT diagram for this system. Suppose that supstance we looking at has three phases solid, liquid and gas. In that case we have critical point between liquid and gas phase, but not between solid and liquid phase. Why? Why solid - liquid coexistence...

Homework Statement What strenght do you need to put mass m in the height h? Homework Equations P=\frac{A}{t} The Attempt at a Solution A=mgh so P=\frac{mgh}{t} Is that mean that your strenght is less if you take mass long in the height h?

Ok just tell me \frac{1}{e^x-x-1}=... what you have done before you put \frac{2}{x^2}?

If I remember well this integral is from Stefan - Boltzmann law. It's value is \frac{\pi^4}{15}. Put e^x in form of the series, use some approximation and you must in the and get Riman zeta function.

I understand what you trying to tell me. But \frac{2}{x^2}-\frac{2}{3 x}+\frac{1}{18}+\frac{x}{270}-\frac{x^2}{3240}-\frac{x^3}{13608}-\frac{x^4}{2041200}+\frac{x^5}{874800}+\frac{13 x^6}{146966400}-\frac{307 x^7}{24249456000}-\frac{479 x^8}{203695430400}+O[x]^9...

Listen to me. I have just this\frac{1}{e^x-x-1}

Open up the brackets?

Ok. I will get \frac{2}{x^2}\sum^{\infty}_{n=0}(-1)^n(\frac{x}{3}+\frac{x^2}{12}+...)^n But I don't have this form \frac{2}{x^2}-\frac{2}{3 x}+\frac{1}{18}+\frac{x}{270}-\frac{x^2}{3240}-\frac{x^3}{13608}-\frac{x^4}{2041200}+\frac{x^5}{874800}+\frac{13...
