answerI need to perform simple mathematical code in Wolfram Mathematica. It calculates the transition matrix using 2 certain dielectric layer, and then this matrix is being built in a 500 degree (500 pairs of such layers).T[n_, d_] := {{Cos[2 \[Pi] n*\[CurlyEpsilon]/1240 d],
I/n Sin[2 \[Pi] n*\[CurlyEpsilon]/1240 d]}, {I n Sin[...

answerHello! Recently I needed to quickly solve equation with logarithms. Without hesitation, I typed it into Wolfram alpha and got the answer. After a while I saw the Step-by-step solution and noticed that all of the natural logarithms it replaces so (because, actually, it's just divided by 1):
Please tell me why he was doing th...

answerI do not understand why Mathematica 10 cannot solve my system of equations.
Do not tell me what is the mistake?lOA = 3.5
lAB = 9.8
lO3B = 7.7
xO3 = -10.5
yO3 = 7.5
phi1 = Range[0, 330 (Pi/180), 30 (Pi/180)]
Solve[
lOA Cos[phi1] - lAB Cos[phi2] == xO3 + lO3B Cos[phi3] &&
lOA Sin[phi1] + lAB Sin[phi2] == yO3 + lO3B...
