Hey guys!

For those of you ahead of my time zone, Happy Lunar New Year! I took the NACLO today. It wasn't math! It was logic on steroids :/. This is a linguistics Olympiad designed to test your knowledge and skills. If you want, I can send you the links (everyone failed in my school, including me :) ).

ACHIEVEMENTS EARNED DURING THE LAST QUESTION: 0

## The Question of the Day - 1/30/2014

Okay, back to what I am good at!

What is the value of the sum –1 + 2 – 3 + 4 – 5 + 6 – 7 …+10,000?

## For those of you interested in Calculus

Find dy/dx of the following equation.

ln(sin y) = ln(cos x), where ln stands for the natural log of x.
