Trigonometric Ratios Trigonometrical Ratio Introduction Concept of Perpendicualr, Base, Hypotenuse Notation of Angles Relations Between Trigonometrical Ratio Trigonometrical Ratio Table Introduction:  "Trigonometry"  is an important branch of mathematics. The word ' Trigonometry' made by two Greek words; trigonon and metron. The word trigonon means a triangle, the word metron means measure. So that we known that Trigonometry is the way were we introduced with the science of measuring an triangles. In 3rd century BC. Concept of Perpendicular (height), Base, and Hypotenuse in a Right Angle Triangle: For any acute angle in a right-angled triangle; Perpendicular is the side opposite to the acute angle; the side adjacent to it is called Base ; Hypotenuse is the side opposite to its right angle. Example: Angle : Let's Consider a BA ray. If this ray rotates through its origin B and takes the position BC, then we say that the angle...

Logarithm Definition Law of Logarithm Product Rule Quotient Rule Power Rule Some other rules of logarithm Special log properties Logarithm Introduction   Logarithm was discovered in 17th century in Europe as to simplify an mathematical calculations . It was a Greek word which means  arithmetic , ratio, and proportion.  If someone asked us, "multiply 10' times 2"  what would do you simply multiple the 2 Ten times like that, 2 X 2 X 2 X 2 X 2 X 2 X 2 X 2 X 2 X 2 = 1,024.  If I said that write it in another way so what you would do you us exponential expression by these you can write it as 2 10  = 1024 If I said that there is another way to solve or write this equation, what is the method? It was Logarithm an another way of thinking to solve exponential equations . What is Logarithm ? In previous classes we study exponential, we known that if 6'raised to the power 3 the resultant is 216. This is known as exponen...
