bernoulli’s theorem ABSTRACT / SUMMARY The main purpose of this experiment is to investigate the validity of the Bernoulli equation when applied to the steady flow of water in a tape red duct and to measure the flow rate and both static and total pressure heads in a rigid convergent/divergent tube of known geometry for a range of steady flow rates. The apparatus used is Bernoulli’s Theorem Demonstration Apparatus‚ F1-15. In this experiment‚ the pressure difference taken is from h1- h5. The

LAST THEOREM I am going to do my project in the field of number theory. Number theory‚ a subject with a long and rich history‚ has become increasingly important because of its application to computer science and cryptography. The core topics of number theory are such as divisibility‚ highest common factor‚ primes‚ factorization‚ Diophantine equations and so on‚ among which I chose Diophantine equations as the specific topic I would like to go deep into. Fermat ’s Last Theorem states

Chapter 5 1. Why is important to help children develop cognitive skills during the preschool year? According to Rike‚ Izumi-Taylor‚ and Moberly (2008)‚ it is the richness of a child’s experiences that directly affects the development of the brain. They say: “[R]ecent brain and educational research clearly shows these neural pathways can be made richer and stronger through appropriate early care and challenging experiences that take place in carefully designed‚ nourishing environments”

The binomial theorem is a simplified way of finding the expansion of a binomial to a certain power. We can of course find the expanded form of any binomial to a certain power by writing it and doing each step‚ but this process can be very time consuming when you get into let’s say a binomial to the 10th power. Example: (x+y)^0=1 of course because anything to the power if 0 equal 1 (x+y)^1= x+y anything to a power of 1 is just itself. (x+y)^2= (x+y)(x+y) NOT x^2+y^2. So expand (x+y)(x+y)=x^2+xy+yx+y^2
