Require an explanation??

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?

In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

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