I can't draw function "sin(x)" in qalc-qt but I can do this in qalc-gtk
is this a bug

Please provide more details.
How are you trying to draw "sin(x)" (using the plot dialog or using an expression, e.g. plot(sin(x)))?
What are the result of this (how does it fail in qalculate-qt)?
Which qalculate-qt version (version number and package type) and which operating system are you using?
