    Just replace each x in the function with the value given when you enter it into your calculator.

    I tried that, but its not counting it correct. For example:

    tan(0.5)=0.00872686 Then \frac{0.00872686-0.5}{0.5^3} which give you -3.930185...which is not correct.

    Your equation is h(x) but in your table the header is f(x) is this correct?

    Maybe you need to change the mode on your calculator; I'm getting 0.370420 for that question.

    Haha. A common mistake. I've made it so many times now that I always watch out for it

    I think it should be in Radian mode.
