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!
