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!?
