START TO LOVE ADD MATHS

Tomorrow is the day whether a history will be acheived or not..
PMR RESULT will come out!!!!
Pray a lot....May Allah gives us the strength and will to accept anything whether it's good or bad.
Dear Form Three students, make sure that you are well prepared...

The main reason for me to write today is... please have a positive mind set for my subject...
Start to love the subject...
Positive thinkers will find the subject easy to learn and achieve A+.

Tips 4 all of u:

1 Interest will enhance learning.

2. Master basic skills, such as algebra, fractions, factorisation and negative numbers.

3. Get used to mathematical symbols and terminology.

4. Understand the mathematical concept and application.

5. Do lots of exercises because practice makes perfect.

6. Do the exercises on your own instead of getting solutions from friends.

7. Pay full attention in the class while your teacher is teaching.

8. Refer to your teacher if you have problems.

9. Do mind mapping to understand lessons especially topics related to applications.

10. Master your own scientific calculator.

11. Revision has to be done earlier, frequent and continuously.
12. Group studies can enhance better understanding and enforce solving methods.
13. Familiar with the past years questions.

If you really practice all those tips , you will find that ADDITIONAL MATHEMATICS is EASY.
These tips were not meant for Form 3 students(Form4 to be...in 2010) but also for Form 4 (Form 5 to be....in 2010)

2010 SEMAKIN HAMPIR

Untuk anak-anak KUSESS...
Sudah bersedia untuk tahun 2010?
Anda mesti sudah bersedia menghadapi cabaran 2010. Terutamanya yang berada di Tingkatan 3 dan 5. Buat persediaan awal untuk PMR dan SPM. Jangan tunggu last minute . Study consistantly.
Kejayaan kamu adalah hadiah terindah untuk ibubapa dan guru-guru...

MORE ON DIFFERENTIATION

Differentiation

Taking limits to find the derivative of a function can be very tedious and complicated. The formulas listed below will make differentiating much easier. Each formula is expressed in the regular notation as well as Leibniz notation.

Constant Rule: If f is a constant function, where f(x) = c, then

Power Rule: If f is a power function, where f(x) = xⁿ and n is a real number, then

Note: The graph of the derivative of a power function will be one degree lower than the graph of the original function.

Note: For an example of a power function question, see Example #6 below.

Constant Multiple Rule: If f is a differentiable function and c is a constant, then

Sum Rule: If f and g are differentiable functions, then

In Leibniz notation,

Note: For an example of the sum rule, see Example #7 below.

Difference Rule: If f and g are differentiable functions, then

In Leibniz notation,

Note: For an example of the difference rule, see Example #8 below.

Product Rule: If f and g are differentiable functions, then

In Leibniz notation,

Note: For an example of the product rule, see Example #9 below.

Quotient Rule: If f and g are differentiable functions, then

In Leibniz notation,

The Chain Rule

The chain rule is used to find the derivatives of compositions of functions. A composite function is a function that is composed of two other functions. For the two functions f and g, the composite function or the composition of f and g, is defined by

The function g(x) is substituted for x into the function f(x). For example, the function F(x)=(2x+6)⁴ could be considered as a composition of the functions, f(x)=x⁴ and g(x)=2x+6. However, it could also be written as a composition of f(x)=(2x)⁴ and g(x)=x+3. Often, a function can be written as a composition of several different combinations of functions.

The chain rule allows us to find the derivative of composite functions. The chain rule states that if f and g are differentiable functions and F(x)=f(g(x)), then F is differentiable and the derivative of F is given by

In Leibniz notation, if y=f(u), u=g(x) and y and u are differentiable functions, then

PERINGATAN UNTUK ANAK-ANAK TINGKATAN 4 DAN 5 2010

Kerja cuti terancang perlu diselesaikan sebelum pulang ke sekolah. Beberapa orang pelajar Tingkatan 4 2010 telah meninggalkan KCT dan modul pengajaran di Dewan Makan.Tiada alasan untuk anda tidak menyelesaikan kerja-kerja tersebut.

INDAH....

Inikah kehidupan yang sebenar
Nama, darjat, pangkat dan kekayaan
Dijadikan kayu ukur bagi setiap insan
Angkuh dan sombong
Hadir dalam diri

Insan harus sedar....
Nilai kemanusiaan lebih penting
Dari nama, darjat, pangkat dan kekayaan...
Allah menjadikan kita sama
Hari akhirat penentu segalanya.....

PERJUANGAN YANG BELUM SELESAI

Khas buat anak-anak yang mengenaliku.....

Perjuangan yang anda lalui masih belum berpenghujung. Teruskan. Lalui hari-hari yang mendatang dengan penuh tekad dan semangat. Penuhi hasrat ayah, ibu dan guru-guru yang mendidikmu untuk melihat anda berjaya dengan cemerlang di dalam SPM. Buat anak-anak KUSESS hadapilah segala cabaran yang mendatang dengan gigih. Usah leka dan lalai...
Buat anak-anak yang mengikuti Projek Gemilang Skor A Selangor 2009 bagi pelajar Sekolah Agama Bantuan Kerajaan, ingat pesanku. Jangan sekali-kali patah semangat. Gagal sekali atau berkali-kali bukan bermakna gagal selama-lamanya.

Kejayaan anda adalah hadiah paling berharga buat seorang guru...... Ingat!! Perjuangan kalian masih belum selesai.

TRIGONOMETRIC FUNCTIONS

In mathematics, the trigonometric functions (also called circular functions) are functions of an angle. They are used to relate the angles of a triangle to the lengths of the sides of a triangle. Trigonometric functions are important in the study of triangles and modeling periodic phenomena, among many other applications.

The most familiar trigonometric functions are the sine, cosine, and tangent. The sine function takes an angle and tells the length of the y-component (rise) of that triangle. The cosine function takes an angle and tells the length of x-component (run) of a triangle. The tangent function takes an angle and tells the slope (y-component divided by the x-component). More precise definitions are detailed below. Trigonometric functions are commonly defined as ratios of two sides of a right triangle containing the angle, and can equivalently be defined as the lengths of various line segments from a unit circle. More modern definitions express them as infinite series or as solutions of certain differential equations, allowing their extension to arbitrary positive and negative values and even to complex numbers.

Trigonometric functions have a wide range of uses including computing unknown lengths and angles in triangles (often right triangles). In this use, trigomonetric functions are often used in surveying, architecture, engineering, and physics. A common use in elementary physics is resolving a vector into Cartesean coordinates. The sine and cosine functions are also commonly used to model periodic function phenomena such as sound and light waves, the position and velocity of harmonic oscillators, sunlight intensity and day length, and average temperature variations through the year.

In modern usage, there are six basic trigonometric functions, which are tabulated here along with equations relating them to one another. Especially in the case of the last four, these relations are often taken as the definitions of those functions, but one can define them equally well geometrically or by other means and then derive these relations.

WHAT HAVE I DONE TODAY.

Today I was discussing the Hari Raya exercises with 4 Intan. Some of them manage to answer all the questions correctly. Well done!!

Be ready with tomorrows lesson. Solution of Triangle is coming up.

Be prepared with your Trigonometric Function basic.
These are the things you should prepare:
1 What is the formula of sine, cosine and tangent?
2 Do you know the word quadrant?
3 In which quadrant that sine , cosine and tangent have positive values?
4 Can you use your calculator wisely? Make sure that you have it tomorrow.
