What is Flutter?
In general, creating a mobile application is a very complex and challenging task. There are many frameworks available, which provide excellent features to develop mobile applications. For developing mobile apps, Android provides a native framework based on Java and Kotlin language, while iOS provides a framework based on Objective-C/Swift language. Thus, we need two different…

Flutter Tutorial
Our Flutter Tutorial provides basic and advanced concepts of the Flutter framework. Flutter is a UI toolkit for building fast, beautiful, natively compiled applications for mobile, web, and desktop with one programing language and single codebase. It is free and open-source. Initially, it was developed from Google and now manages by an ECMA standard. Flutter apps use Dart…

Applications of Trigonometry
Its applications are in various fields like oceanography, seismology, meteorology, physical sciences, astronomy, acoustics, navigation, electronics, etc. It is also helpful to measure the height of the mountain, find the distance of long rivers, etc.

Trigonometry Examples
There are many real-life examples where trigonometry is used broadly. If we have been given with height of the building and the angle formed when an object is seen from the top of the building, then the distance between object and bottom of the building can be determined by using the tangent function, such as…

Trigonometry Basics
The three basic functions in trigonometry are sine, cosine and tangent. Based on these three functions the other three functions that are cotangent, secant and cosecant are derived. All the trigonometrical concepts are based on these functions. Hence, to understand trigonometry further we need to learn these functions and their respective formulas at first. If…

Trigonometry Identities
The three important trigonometric identities are: sin²θ + cos²θ = 1 tan²θ + 1 = sec²θ cot²θ + 1 = cosec²θ

List of Trigonometry Formulas
The Trigonometric formulas or Identities are the equations which are true in the case of Right-Angled Triangles. Some of the special trigonometric identities are given below – Pythagorean Identities sin²θ + cos²θ = 1 tan2θ + 1 = sec2θ cot2θ + 1 = cosec2θ sin 2θ = 2 sin θ cos θ cos 2θ = cos²θ –…

Unit Circle
The concept of unit circle helps us to measure the angles of cos, sin and tan directly since the centre of the circle is located at the origin and radius is 1. Consider theta be an angle then, Suppose the length of the perpendicular is y and of base is x. The length of the…

Trigonometry Angles
The trigonometry angles which are commonly used in trigonometry problems are 0°, 30°, 45°, 60° and 90°. The trigonometric ratios such as sine, cosine and tangent of these angles are easy to memorize. We will also show the table where all the ratios and their respective angle’s values are mentioned. To find these angles we have to…
