hi ! I have some problem (Mathematica 6) - when I type Manipulate[Plot[If[x < 0, n Sin[x], Cos[x]], {x, -10, 10}], {n, 0, 1}] all is ok, but when i try: M[x_]:=If[x < 0, n Sin[x], Cos[x]], {x, -10, 10}] and then Manipulate[Plot[M[x], {x, -10, 10}], {n, 0, 1}] it doesn`t work - I cannot manipulate varible of n. Whay ?
