Hi,
when I run those commands in mathematica:
y[x_,A_]:=Sin[x]+A+5
Plot[{y[x,5],y[x,6]},{x,0,5}]
z[x_]:=D[y,x]
Everything seems to go well.
But when I trie to plot the derivative:
Plot[{y[x,5],z[x]},{x,0,5}]
I allways have these errors:
Plot::plnrz[x] is not a machine-size real number at x= 2.0833333333333333`*^-7
...
What am I doing wrong ?
I allready tried to change the arguments of z[] to z[x,4], z[x,A] etc...
There's nothing about plotting derivatives on the quick tutorial.
Any help is really appreciated.
I uploaded my mathematica file here http://s47.yousendit.com/d.aspx?id=0LG6F35A7OTY2SVEC7L1T6GXA
Thanks in advance
