You can start by following the instructions and filling out the table by plugging the given values into the provided formulas. Then come back with the results of your "discussion".

I tlooks pretty straight forward, to me. Plug in the values and do the arithmetic. If you have a nice calculator, you can just codde the function and get it to tell you the values.

I think I wouldn't worry too much about the x-column. 11/360 just isn't a real nice value, before or after facting out \(\displaystyle \pi\).

But i dont how they solve the 5 degree..
i mean how they do it...
i want help in it..

To change degrees to radians multiply by pi/180. 5° = pi/36 radians.
(If that isn't the question, I'm sorry. It doesn't show up well for me.)

What? Why is it different from the others? Just plug in the value of x and evauate the expression.

Start with the conversion 11º = 11/360 = 0.03055...

x - (x^3)/6

0.03056 - (0.03056^3)/6 = 0.03056

x - (x^3)/6 + (x^5)/120

0.03056 - (0.03056^3)/6 + (0.03056^5)/120 = 0.03056

That's just the general idea. I didn't use enough decimal places for either of those to make much difference. You use more decimal places and you will get different results. Use at least 10.
