## Trigonometric Function Formulas

You know that we have Hypotenuse – the longest side Base – the third side Perpendicular – the other side opp to the angle in a right triangle Similarly, the six trigonometric functions are: Sine Cosine Secant Cosecant Tangent Cotangent Now let’s study the basic trigonometry formulas. The Trigonometric properties/Formulas are given below:

## Associative Property Formula

The associative property is the core concept in mathematics that shows the property of some binary operations. In propositional logic, associativity is a valid rule of replacement for the expressions in logical proofs. According to associative property law, it states that you can add or multiply regardless of how is the numbers are grouped. Associative property in simple terms refers to the grouping of numbers. It is mainly used to regroup things and any time type of computation depends on things being regrouped. Associative Property of Addition a + (b…

## Cos Square theta Formula

The function of an angle i.e the angles and sides relationships is given by trigonometric functions. Sine, cosine, tangent, cotangent, Cos, Cosec are the trigonometric functions. We have different trigonometric values for these trigonometric functions for various angles like 30 0, 600, etc. To classify the trigonometric functions, the angles of Sine, cosine, and tangent are the primary ones. Cos2 theta formula Cos 2 theta= 1 – sin2 theta Examples of Cos squared theta formula Question: What is the value of cos square x, if Sin x = ⅗? Solution: Cos 2 x = 1 – Sin2 x = 1…

## Sin Tan formula

The law of sin or Tangent which is also called as a sin-tangent formula or sin-tangent rule is the ratio of the sine of the angle to the cos of the angle in the tangent formula Tan Theta = Opposite / Adjacent sin Theta = Perpendicular / Hypotenuse Sin – Tan x formula The Tan Theta is the ratio of the Opposite side to the Adjacent, where (Θ) is one of the acute angles Tan Theta = Opposite / Adjacent sin Theta = Perpendicular / Hypotenuse Tan alpha Questions Out…

## PROFIT MARGIN FORMULA

Probably the most important margin used by businesses to know the total profit percentage over a period of time. When net profit is divided by sales, the product we get is the profit margin. Usually used by small companies for comparing similar industries. It is denoted in percentage. The more profitable the better. Profit Margin=Total Income/Net Sales GROSS PROFIT MARGIN FORMULA Gross Profit Margin=Gross Profit/Net Sales SOLVED EXAMPLES Question 1: Find the profit margin when you buy a pen for Rs. 100 and sell it for Rs. 150. Solution: Given Net Sale = Rs.150 Net Profit = Rs. 150…

## GROSS PROFIT FORMULA

Gross profit is the total revenue minus cost of things sold. It is the company’s profit before all interest and tax payments. Gross profit is also called gross margin. Find below the formula to calculate the gross profit of a company. GROSS PROFIT FORMULA Back to Top Find the formula for gross formula, EXAMPLES OF GROSS PROFIT Back to Top Some solved examples of gross profit are given below, SOLVED EXAMPLES Question 1: If the cost of a fan is 5.30 dollar and sold at 7.90 dollar. Find the gross profit?…

## Algebraic Identities For Class 9

Algebra is a part of Mathematics in which general symbols and letters are used to represent quantities and numbers in equations and formulae. There are two parts in algebra – Elementary algebra and Modern algebra (Abstract algebra). Algebra formulas for class 9 include formulas related to algebra identities or expressions. Algebra Identities chapter is introduced in CBSE class 9. This is a little tricky chapter where one needs to learn all the formula and apply them accordingly. To make easy for them, we at Byju’s provide all the formulas on a single…
