 Author Comment/Response Paco 12/29/09 10:09am After introducing these parameters in steps: {c0GaN = 5.1850, a0GaN = 3.1884, c0InN = 5.70374, a0InN = 3.53774, c0AlN = 4.98089, a0AlN = 3.11197, C11GaN = 374, C12GaN = 138, C13GaN = 101, C33GaN = 395, C44GaN = 98, C11InN = 237, C12InN = 106, C13InN = 85, C33InN = 236, C44InN = 53, C11AlN = 395, C12AlN = 137, C13AlN = 107, C33AlN = 404, C44AlN = 117} {c0[x] = x c0InN + (1 - x) c0GaN, a0[x] = x a0InN + (1 - x) a0GaN, C11[x] = x C11InN + (1 - x) C11GaN, C12[x] = x C12InN + (1 - x) C12GaN, C13[x] = x C13InN + (1 - x) C13GaN, C33[x] = x C33InN + (1 - x) C33GaN, C44[x] = x C44InN + (1 - x) C44GaN} {f[x] = (a0[x] - a0GaN)/a0[x], \[Nu][x] = C13[x]/(C11[x] + C12[x])} {b1[x] = Sqrt[c0[x]^2 + a0[x]^2], \[Lambda]1[x] = ArcTan[c0[x]/a0[x]], \[Beta]1[x] = \[Pi]/2} {R = Cos[\[Lambda]1[x]], S = Cos[ \[Beta]1[x]]} I define the following equation: hF1 = ((b1[x]*R)/( 2 f[x]))*(1 + ((1 - (1 - (S^2*\[Nu][x])))/( 4 \[Pi]*(1 + \[Nu][x])*R^2)))*Log[hF1/b1[x]] AND A VERY LARGE OUTPUT IS GENERATED; Well I want to Plot[hF1,{x,0,1}] but it runs "infinitely" without solution; I TRIED TO SIMPLIFY and FULLSIMPLIFY (AND OTHER OPTIONS) USING THE ASSUMPTION 0 < x < 1 AND I AM NOT ABLE TO MAKE SHORTER THE SOLUTION (again infinite running). PLEASE, HAVE YOU A METHOD AT LEAST TO FIND AN APPROXIMATED SOLUTION TO PLOT?, I DO NOT NEED A BIG ACCURACY IN THE SOLUTION OF EACH "x"... URL: ,
