Ok so i have the next exercise.

I didn't had any problems solving a) and b)

What about c?

Can anyone tell me how to resolve it?

I googled it and found out that's Si(x)(whatever that is) and i don't know about what's that since i'm just last grade of high school.

Any help?

Hi;

**In mathematics, you don't understand things. You just get used to them.****If it ain't broke, fix it until it is.** **A number by itself is useful, but it is far more useful to know how accurate or certain that number is.**

You may use taylor expansion about t=0 for c)
