**Probability** is the study of the chances a particular event has, as any event happening has certain outcomes. So the measure of probability ranges from ‘0’ (event not happening-**0%chance**) to ‘1’ (event happening for sure-**100%chance**).

# What is Function & Different Types of Functions (mathematics)

### Math Functions, Relations, Domain & Range

A function ‘f’ is a relation between two sets which converts an input into an output. A function with Domain ‘x’ and Range ‘y’ is denoted by **f: X->**** Y**.

# Sine, Cosine and Tangent in Four Quadrants

## Sine, Cosine and Tangent (Trigonometry Four quadrants)

The 6 trigonometric functions when graphed in an x-y coordinate plane, give different measurements based on their side and angle. The sign of the trigonometric functions depends on how the angle is formed.

# What units of measurement are used for data storage?

## Fundamental unit of measurement for data.

Measurement for data is the most commonly used logic in our everyday life. To buy something in a grocery store, the number of items bought is counted or measured. In fact to even pay the bill, money is measured! So without proper measurement units, our everyday life would be almost impossible!

# What is Square root functions

**Square root functions** (for example: y= √x) is defined as the function where the output ‘y’ when multiplied by itself (squared) gives the input ‘x’. The symbol **‘√’**is called the **‘radical symbol’** and the general form of any square root function is given by:

# What is Area of Plane Shapes :Triangles,Rectangle,Square,Circle

** Area of Plane Shapes -> In Geometry,** the dimensions such as length, width of any geometric structure gives us important information about the structure’s area, perimeter etc. This data and measurements are very useful in our daily life as it helps us calculate things like fencing for our back-yard, area of the space occupied etc.

# What is Trigonometry

Trigonometry can be used in finding the measure of the angles, their function values and also the sides of a triangle. The 6 trigonometric functions can be used to find the remaining side or angle in a right triangle. These calculations give rise to **trigonometric ratios in a right triangle**.

# Introduction to Trigonometric functions

In Trigonometry functions, angles and sides are widely used as they give rise to the Trigonometry functions. Based on the angles, there are **6 basic Trigonometric functions**, out of which 3 are primary functions and the remaining three can be derived from the primary functions.

# What is proportionality? – (mathematics)

**proportionality => **Proportion is the equality shared between two ratios and when two separate ratios are equal to each other, they are said to be ‘in proportion’. Proportion is also the balance maintained between two sets of numbers divided with each other or two ratios.

**Ratio** is the comparison between two quantities which are similar and to compare they are divided by each other.
