All about Mathematics

The area of study known as the history of mathematics is primarily an investigation into the origin of discoveries in mathematics and, to a lesser extent, an investigation into the mathematical methods and notation of the past. Before the modern age and the worldwide spread of knowledge, written examples of new mathematical developments have come to light only in a few locales. The most ancient mathematical texts available are Plimpton 322 (Babylonian mathematics c. 1900 BC), the Rhind Mathematical Papyrus (Egyptian mathematics c. 2000-1800 BC) and the Moscow Mathematical Papyrus (Egyptian mathematics c. 1890 BC). All of these texts concern the so-called Pythagorean theorem, which seems to be the most ancient and widespread mathematical development after basic arithmetic and geometry. The Greek and Hellenistic contribution greatly refined the methods (especially through the introduction of deductive reasoning and mathematical rigor in proofs) and expanded the subject matter of mathemat...

Since the fourth century AD, Pythagoras has commonly been given credit for discovering the Pythagorean theorem, a theorem in geometry that states that in a right-angled triangle the square of the hypotenuse (the side opposite the right angle), c, is equal to the sum of the squares of the other two sides, b and a—that is, a2 + b2 = c2. Here is the steps to prove Pythagorean Theorem... 1. make 4 congruent triangles 2. Then, arrange them become rhombus 3. Look the yellow one, the side=c 4. So we know that the area of rhombus + the area of 4 right triagles are the area of square Here is another way to prove Pytagorean theorem

Pythagoras was an Ionian Greek philosopher, mathematician, and founder of the religious movement called Pythagoreanism. Most of the information about Pythagoras was written down centuries after he lived, so that very little reliable information is known about him. He was born on the island of Samos, and may have travelled widely in his youth, visiting Egypt and other places seeking knowledge. The Pythagorean question, then, is how to get behind this false glorification of Pythagoras in order to determine what the historical Pythagoras actually thought and did. In order to obtain an accurate appreciation of Pythagoras' achievement, it is important to rely on the earliest evidence before the distortions of the later tradition arose. The popular modern image of Pythagoras is that of a master mathematician and scientist. The early evidence shows, however, that, while Pythagoras was famous in his own day and even 150 years later in the time of Plato and Aristotle, it was not mathematic...

Let’s make Education revolution in Indonesia Begitulah kata-kata yang terbesit di dalam hatiku ketika melihat sosok Bu Sitti Maesuri. Beliau adalah dosen Matematika di Jurusan saya yaitu Pendidikan Matematika Internasional. Di jurusan saya bertujuan untuk mencetak tenaga-tenaga pengajar di sekolah bertaraf internasional. Selama 2 semester ini saya selalu diajar oleh beliau. Beliau mengajar mata kuliah English 2 dan Learning Theory. Beliau adalah wanita yang sangat cerdas karena beliau telah menyelesaikan studi PhD di Queensland University melalui jalur beasiswa. Selain itu, Beliau juga memberikan kontribusi yang sangat besar di dunia pendidikan melalui buku yang ditulisnya berjudul Internet for Teacher Professional Development yang dipublish oleh Jerman “LAP LAMBERT Academic Publishing AG & Co. KG”. Buku ini berisi tentang penelitiannya selama di Australia tentang internet sebagai media pembelajaran dan pengajaran. Beliau menggagas pembelajaran melalui internet. Melalui buku yang d...

Siswa SMU yang duduk di bangku kelas 3 memiliki banyak sekali kesibukan dan tanggung jawab untuk mempersiapkan kelulusannya. Mulai dari Ujian Semester, Ujian Praktek, Ujian Akhir Sekolah hingga Ujian Nasional. Dari berbagai macam ujian tersebut, tentu para siswa harus mempersiapkan segala sesutunya dengan matang. Mereka harus bekerja keras untuk belajar hingga malam, mengikuti kursus, latihan soal-soal, mengikuti Try Out, dll. Arrrggghh, kepala rasanya nyut-nyutan karena harus belajar lagi dari materi kelas1 hingga kelas 3.Kalau udah kelas 3, rasanya g ada waktu buat maen. Masa-masa kelas 3 SMA merupakan masa-masa yang sulit bagi mereka. Akhirnya Ujian Nasional telah selesai digelar. Rasa deg-degan dan kekhawatiran bercampur aduk jadi satu. Rasanya belum tenang kalo belum diumumin hasilnya. Waktu yang ditunggu-tunggu telah datang, yaitu pengumuma hasil UNAS. Luapan kegembiraan terpancar di wajah mereka yang lulus UNAS. Berbagai macam cara yang mereka lakukan untuk mengekspresikan k...
