Percentage, which is clear by the name, implies “for every hundred”. This concept is actually developed to make the comparison of fractions easier by equalizing the denominators of all fractions to a hundred. (Read article “Profit and Loss”) OR In mathematics, a percentage is a number or ratio that can be expressed as a fraction of 100.
In this section, we will discuss about what actually are algebraic expressions? How are they written? I know a lot must be going in your minds right now. Don’t you worry I’m here for you? Basically, algebraic expressions are made up of integers constant, variables, and algebraic operations. For example: 5×2 + 3xy – 2 ,
As in the last section we have learned about the complementary angles and heights and distances, in this section we will learn about Trigonometry (Value Based and Simplification). We learned the values of 30o, 45o, 60o, 90o of different trigonometric functions, here will see how we find out the values of the other trigonometric values. Signs
As in the last section we learned about the basics of trigonometry, in this section we will continue further with two topics i.e., Complementary Angles and Heights and Distance. In the first part we will first cover complementary angles and in the next heights & distances. So, let’s start with the first part. Complementary angles: – Do
