INTRODUCTION OF BASIC ALGEBRA

BASIC ALGEBRA What is Algebra?            Algebra is the branch of mathematics that uses letters in place of some unknown numbers. You've been using algebra since your early schooling, when you learned formulas like the  area of a rectangle , with width  w , height  h : A  =  w  ×  h We used  letters to stand for numbers.  Once we knew the width and height, we could substitute them into the formula and find our area. Another one you may have seen is the  area of a circle , with radius  r : A  = π r 2 As soon as we know the length of the sides, we can find the area. Literal numbers  (the letters used in algebra) can either stand for  variables  (the value of the letter can change, like the  w ,  h  and  r  in the examples of the area of a rectangle and the area of a circle) or  constants  (where the value does not change), fo...

INTRODUCTION OF TRIGNOMETRY

Trigonometry  (from  Greek   trigōnon , "triangle" and  metron , "measure" [1] ) is a branch of  mathematics  that studies relationships between side lengths and  angles  of  triangles . The field emerged in the  Hellenistic world  during the 3rd century BC from applications of  geometry  to  astronomical studies .  The Greeks focused on the  calculation of chords , while mathematicians in India created the earliest-known tables of values for trigonometric ratios (also called  trigonometric functions ) such as  sine . [3] Throughout history, trigonometry has been applied in areas such as  geodesy ,  surveying ,  celestial mechanics , and  navigation . [4] Trigonometry is known for its many  identities , [5] [6]  which are equations used for rewriting trigonometrical expressions to solve equations, to find a more useful expression, or to discover new re...
