when i apply limit(x^3-​6*(x-sin(x​)))/(6*(x^​4)*sin(x))​, i am getting: ans = 0; but correct ans. is 1/120; Am i doing something wrong?can i replace x by theta?

when i apply

limit(x^3-6*(x-sin(x)))/(6*(x^4)*sin(x))

i am getting: ans = 0; but correct ans. is 1/120; Am i doing something wrong? can i replace x by theta to get the same value:1/120

 syms x

 a = limit(( (x^3)- 6* (x - sin(x)))/(6* ((x^4))* sin(x)))

That is, some of your () were misplaced.

Actually tried limit(x^3-6*(x-sin(x))) upon (6*(x^4)*sin(x)) and question was

 limit([( (x^3)- 6* (x - sin(x)))/(6* ((x^4))* sin(x))])

check [] in equation.
