sine-integral

Si(x)=?(sin t)/t dt, a=0, b=x

This function was constructed by using the Second Fundamental Theorem of Calculus (Construction Theorem for Antiderivatives). The function f(t)=(sin t)/t used to give mathematicians a lot of grief since its antiderivative is not an elementary function and that the limit as t approaches 0 of (sin t)/t is 0/0 (we do know that that limit is approximately 1 by using L'Hopital's rule). The Construction Theorem made calculating values of Si(x) to any degree of accuracy easy. This is useful as some scientists and engineers use it all the time in fields such as optics and magnetism.

Si(1)=0.95, Si(2)=1.61, Si(3)=1.85 . . .

sidetracked

Social context: Meet (as in see again/ or for the first time) a person who you don't really appreciate being with, and getting stuck with him/ her.

Jonathan, Mark and Darriel are waking towards the balcony in a party. On the way, Darriel is spotted by her high-school colleague, who is a nerd (while Darriel is really cool) and she HAS to talk to her for a while.
Once in the balcony, Mark says:
- Hey, where is Darriel??
Jonathan: She got sidetracked!

Sineth

They are Introverted, but the best companion one can have if they're close enough to them. Highly lovable, Sexy and addictive. Sineths are so intelligent, mostly love learning astrophysics and mathematical stuff. And they have good artistic abilities too. Once you get into them, you never get bored.

I talked to Sineth last night like more than an hour. And we played games together too.
