(1921)‚ Time Magazine’s Person of the Century (1999) Einstein’s Contribution to Mathematics While Einstein was remembered for his contributions to physics‚ he also made contributions in mathematics. He contributed several equations to calculus and geometry‚ ten of which are called the Einstein Field Equations. He first published these equations in 1915. One of these equations demonstrates how stress-energy inflicts curvature of space-time. Born: Dec 25‚ 1642‚ in Woolsthorpe-by-Colsterworth‚ Lincolnshire

Many results in geometry can be shown or demonstrated by construction and measurement. For example‚ we can draw a triangle and measure the angles to show or demonstrate that the angle sum of a triangle is 180 ° . However this does not prove that the angle sum of any triangle is 180 ° . To prove this and other geometrical results we use a process called deduction ‚ in which a specific result is proved by reasoning logically from a general principle or known fact. When setting out proofs

Verify that ABCD is a trapezoid. SOLUTION: First graph the points on a coordinate grid and draw the trapezoid. SOLUTION: The trapezoid ABCD is an isosceles trapezoid. So‚ each pair of base angles is congruent. Therefore‚ ANSWER: 101 2. WT‚ if ZX = 20 and TY = 15 SOLUTION: The trapezoid WXYZ is an isosceles trapezoid

The problem is believed to have been first introduced by Greek astronomer Ptolemy back in 150 AD1 and then eventually noticed by 17th century Arabic mathematician Abu Ali al Hassan ibn Alhaitham (whose name was later Latinized into Alhazen)2 .

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 study of mathematics as a subject in its own right begins in the 6th century BC with the Pythagoreans‚ who coined the term "mathematics" from the ancient Greek μάθημα (mathema)‚ meaning "subject of instruction".

Study Coordinate systems form a common frame of reference for description of positions and on the other hand‚ coordinates are simply an ordered set of numbers that are used to describe the positions or features in coordinate system. Transformation parameters are required to move from one system to another.

MATHEMATICS CURRICULUM FOR SECONDARY COURSE RATIONALE Mathematics is an important discipline of learning at the secondary stage. It helps the learners in acquiring decision- making ability through its applications to real life both in familiar and unfamiliar situations. It predominately contributes to the development of precision‚ rational and analytical thinking‚ reasoning and scientific temper. One of the basic aims of teaching Mathematics at the Secondary stage is to inculcate the skill
