I tried worksheet but nothing.
I tried to use evalc(cos...) function but again nothing.
Why cant insert 1 in first TextField and get result in second
TextField 0.5403023059 and not cos(1)!?
Is that possible?
In classic worksheet is OK:
x:=1:
evalf(cos(x));
but in maplet evalf, evalc... gives nothing!?
