# Thread: help with tan equation

1. ## help with tan equation

Consider the following function.

(a) Evaluate h(x) for the following values of x. (Give your answer correct to six decimal places.)

xf(x) 1Enter a number.
1 0.5 Enter a number.
2 0.1 Enter a number.
3 0.05 Enter a number.
4 0.01 Enter a number.
5 0.005 Enter a number.

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

3. 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.

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

5. Actually yes, lol, I dont know how they messed that up, but yes that is what it shows on the website.

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

7. Shouldnt it be in degrees?

8. 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.
