I believe in me
In the video, the boy is Dalton. He is very convident. He can stand fearless in front of many people, twenty thousand people. He told that “You believe in me because I believe in me”. If we believe in ourself, we can do anything, we can be anything, become anything, and etc. “Do you believe in me?”. People believe in you, if you believe in yourself. We can do anything if we believe in ourself. Dalton believe in yourself, he need people believe in him, he need people help him.
What ever we do, not only for our generation but also to next generation. Dalton believe that what ever we do if we believe in ourself.

How difficult to explain mathematics
My name is Isnaini Nurul Noviana. My partner is Esti Nur Kurniawati. We discuss about Differential Equations, the chapter is “The homogenous Linear equation with constant coefficients. In this section we consider the special of the nth-order homogenous linear equation in which all of the coefficients are real constants.
Distinct Real roots
If we have roots which have different, the general solution is y = C1e^M1X +C2e^M2X+…+CNe^MnX, where C1, C2, C3,…,Cn are arbitrary constants.
Repeated real roots
If we have roots which have repeated, the general solution is y = (C1+C2X)e^MX.
This activity was held on Friday, January, 9th 2009 at 01.10pm until 02.00pm, in KOPMA UNY. I started to discuss the differential equation, with the theorem, then exercise. With many exercise, Esti have can do the assignment in the differential equation book, so I am not review my explanation mathematics. This chapter have ever been learn.
