gnuplot won't draw a function sqrt(2/10)*sin((

Question

Gnuplot won't seem to draw a function:

sqrt(2/10)*sin((3.14/10)*x)

Could anyone tell me why. I tried to draw it in Wolfram alpha and it worked compleetely fine there.

Answer 1

Most probably the 2/10 is computed as integer division and zeros everything else out.

Change it to:

sqrt(2.0/10.0)*sin((3.14/10.0)*x)

Or:

sqrt(0.2)*sin(0.314*x)
