- A function is a rule that maps an input number (independent variable) to a unique output number (dependent variable).
- To determine if a rule describes a valid function, you can plot points from the rule on a graph and check that each input only maps to one output using a vertical ruler.
- For a rule to describe a valid function, its domain must be restricted if multiple outputs are possible for any single input. The domain is the set of possible inputs, and the range is the set of corresponding outputs.
This document outlines a plan to compact the mathematics curriculum for Form 2 students in Malaysia in 2010. It lists topics that will no longer be taught, additional topics, and suggested activities. Key points include removing some computation topics and focusing more on concepts like transformations, loci, and solid geometry through exploration with technology and hands-on models.
Learn how to involve your entire organization with an all hands on line philosophy. Double profits effortlessly and increase your contact effectivenes.
This document is the question paper for a mathematics exam consisting of 40 multiple choice questions. It provides instructions for answering the questions, including that students should blacken only one answer for each question on the answer sheet. It also lists several mathematical formulas that may be helpful in answering the questions. The questions cover a range of mathematics topics including arithmetic, algebra, geometry, statistics and graphs.
This document lists the rulers of Afghanistan from 1709 to 2009, along with the years they ruled. It begins with the Hotaki dynasty rulers Mirwais Shah, Mahmood Shah, and Ashraf Shah who ruled from 1709 to 1729. It then lists the rulers from the Durrani dynasty, including Ahmad Shah Durrani from 1729 to 1747. Afterward it notes various kings and leaders up to Hamid Karzai, who was president from 2004 to 2009. The document is attributed to Abdul Wali Mustafa and appears to be a history of Afghan political leadership over centuries.
This document provides information about the 20th century artist Lucian Freud and his realistic figurative painting style. It summarizes Freud's early life and career, describes some of his most famous paintings like The Refugees and A Woman Painter in detail, and suggests activities and tasks teachers could use to explore Freud's style of portraiture with students. These include recreating Freud's compositions, focusing on tones and shapes in faces, and cross-curricular connections to math, history, and PSHE. The document aims to be a useful resource for teaching drawing and portraiture through the lens of Freud's highly realistic approach.

1. The document contains 14 multi-part mathematics questions involving sequences and series.
2. Many questions involve finding the common ratio (r), first term (a), or sum (Sn) of sequences that satisfy given properties or equations relating to arithmetic and geometric progressions.
3. Proofs are provided that certain expressions are arithmetic or geometric progressions, or that certain series representations are valid.
This document contains a chapter on complex numbers from an Oxford textbook. It includes examples of adding, multiplying, dividing and simplifying complex numbers. It also covers topics like modulus, argument and solving complex number equations. Several worked examples are provided with step-by-step solutions.
A function is a relationship where one quantity depends on another. The area of a circle is a function of its radius, as the area changes when the radius changes. Derivatives show the rate of change of a function at a point and represent an infinitesimal change in the function with respect to one of its variables. Optimization problems aim to find the maximum or minimum value of a function subject to constraints.

With an increasing number of applications being deployed in the cloud, this trend will soon touch performance testers within every organisation. This presentation will dispel the hype, tell you what you need to know to embrace this opportunity, and answer the following questions:
* What are the challenges specifically related to performance testing cloud-based applications?
* What are some common performance problems seen in cloud-based applications, and how can you test for them?
* How will cloud-based load generators help your performance testing?
Don't get left behind! A solid understanding of cloud concepts will be invaluable to your testing career.

1. Lekcja
Temat: Pole magnetyczne prądu.
1. Doświadczenie Oersteda (1820 r.)
Pod przewodnikiem umieszczamy igłę magnetyczną. Igła wskazuje kierunek północ – południe.
Kiedy przez przewodnik płynie prąd igła magnetyczna odchyla się od wcześniej wskazywanego
kierunku.
Wniosek:
Wokół przewodnika, przez który płynie prąd
powstaje pole magnetyczne.
2. Pole magnetyczne wokół prostoliniowego przewodnika z prądem.
Linie sił pola magnetycznego
wokół prostoliniowego przewodnika
z prądem mają kształt współśrodkowych okręgów otaczających
przewodnik.
2. Zwrot linii sił wyznacza się za pomocą reguły prawej ręki:
Jeśli prawą dłonią obejmiemy przewodnik tak, że kciuk wskaże
kierunek i zwrot prądu w przewodniku, to pozostałe cztery
zagięte palce wskażą jaki jest zwrot linii sił pola
magnetycznego.
3. Pole magnetyczne
zwojnicy (solenoidu) z prądem.
Pole magnetyczne zwojnicy z prądem na zewnątrz przypomina pole magnesu sztabkowego, a
wewnątrz zwojnicy jest polem jednorodnym (linie sił tego pola są do siebie równoległe).
Bieguny magnetyczne zwojnicy z prądem wyznacza się za pomocą reguły prawej
ręki:
Jeżeli prawą ręką obejmiemy zwojnicę tak, aby wszystkie cztery palce wskazywały zwrot prądu w
zwojnicy, to odchylony kciuk wskaże północny biegun magnetyczny powstałego pola magnetycznego.
4. Przykłady:
3. a) Wyznacz bieguny magnetyczne zwojnicy z prądem.
b) Jak oddziałują z sobą zwojnica i obwód kołowy?
c) Jak należy dopiąć do zwojnicy źródło napięcia, aby odpychała magnes?
