Summary: plot2d(acot(x)) signals an error and doesn't plot

Initial Comment:
plot2d(acot(x),[x,-10,10]) signals an error about 0.0 not being in the domain of acot.

But plot2d(acot(x+1d-10),[x,-10,10]) works.

I think COERCE-FLOAT-FUN is not catching the domain-error condition that the new trig function code is producing.

Plot works now.  However, the message about 0.0 not being in the domain is
still printed.  That's probably ok.
