 Author Comment/Response Sandra Ugrina 03/24/09 12:43pm Dear Mathematica users, I am new to Mathematica and I am trying to start off with a simple example. I am trying to evaluate lux below over a range of k (k=[0.01:10]. lux[k_] := (k Coth[2 k] + 2 k^2 Csch[2 k]^2 - 1)/(2 k^4) However, I am getting a following error: SetDelayed::write: "Tag Times in ((-1+k\Coth[2\k]+2\k^2\Csch[2 \ k]^2)/(2\k^4))[k_] is Protected. " I was able to plot the above function of k when expressed as: lux= (k Coth[2 k] + 2 k^2 Csch[2 k]^2 - 1)/(2 k^4) Plot[lux,k,{0.01,10}] How do I get the actual values of lux. It looks like a silly problem yet I can't get it to work. Any is appreciated! URL: ,
