It's true, lifestyle, people, things, success, and money can enhance your happiness, but that's only half the equation. The other half of the equation depends solely on you. I am sure you have heard of people, or perhaps you are one of those people, who have everything money can buy and still aren't happy. Then there are those that are joyous whether they have or don't have things or partners in their life. Why is that? People make a choice to be happy, and it's not just by saying it, it's truly
Title: Developing learners` understanding of quadratic functions and solving quadratic equation. Research problem During teaching practice learners had problems in solving quadratic equations, when learners were taught how to solve problems they don`t care about understanding the nature of the problem and steps to solve the problem. They tempt to memorize how the problems are solved without understanding them. Mathematical pedagogical content knowledge Pedagogical content knowledge refers to the
market models. The component of the market model approach developed by Labys (1973) is the basic structure models in the analysis of agricultural commodity markets .the model according Labys (1973) suggests that for a particular commodity, four equations supply, demand, price and stock (commonly used as an identity to reveal the market clearing condition) are used simultaneously. However as noted by Abdel Hameed et al. (2009) more complex structures of the market behaviour have been developed from
The course Teaching Secondary School Mathematics was very interesting and informative. As I reflect on this course I recognize that it has brought a lot of information into perspective. My classmates and I, at first, found this very tedious but we gradually got a sense of appreciation for the wealth of knowledge we gained from this experience. Among some of the points emphasised were how to write unit plans and lesson plans implementing the 5E’s. It was reiterated that these plans were to be student-centred
Quadratic Equations: Introduction: Quadratic equation is a polynomial equation of the 2nd degree. The word ‘quadratic’ comes from the Latin word quadratus which represent the word ‘square’. Quadratic equation is an equation which can be written in the form of ax2 + bx + c = 0, where a and b are coefficients of x2 and x respectively and c is a constant. The coefficient of x2 cannot be zero and the expression ax2 + bx + c is called as ‘quadratic expression’. For example, 4x2 + 5x + 2 = 0 is a quadratic
of T using the Euler-Lagrange equation is the problem under calculus of variations. Let suppose M is defined by an integral in the form: M=∫_x1^x2▒L(x,y,y^' )dx (13) Here, M is called the functional and has a constant extreme value if the Euler-Lagrange equation is satisfied. The Euler-Lagrange equation is: ∂L/∂y-d/dx (∂L/(∂y^' ))=0 (14) *Note: The derivation of the Euler-Lagrange equation will not be a part of this exploration. So, to solve Euler-Lagrange equation, we might substitute the value
know that, double-entry bookkeeping system is established by Luca Pacioli. Without double-entry bookkeeping system, we cannot analyse the financial status of a business. ACCOUNTING EQUATION The foundation accounting equation is the relationship between assets, liabilities, and equity. It is a basic accounting equation used to balance all of the businesses account (Wikipedia 2017). For example, the double-entry bookkeeping system is a famous system in the accounting world. Most of the businesses using

In this experiment, a reaction of oxalic acid and permanganate was used to determine the rate law and rate constant of that reaction. The rate law is an equation that uses the concentrations, the orders of the reaction and the rate constant to calculate the rate. The reaction consisted of water and oxalic acid being added to a Pyrex tube. After a few seconds of stirring that solution, permanganate was added and a timer was used to calculate how long it would take for the solution to go from dark
Experiment 9 DC Solenoid Control Using a Transistor and Arduino UNO Team Members Sahil Anand (Leader) UIN-675358955 sanand22@uic.eduSagar Pawar UIN-652748958 Anirudh Madhavan UIN-657447988 Jayant Lamba UIN-660595696 Mohammad Rezwan Sheikh UIN-671433501 SUMMERY The main purpose of this experiment was to control a DC solenoid using a power transistor (MOSFET)and an Arduino UNO rev3 microcontroller. We had the opportunity to operate the solenoid directly in ON/OFF state, also the digital output channel
