Area of largest Circle inscribed in N-sided Regular polygon in C Program?
An n-sided regular polygon inscribed in a circle, the radius of this circle is given by the formula, r = a/(2*tan(180/n))Suppose a polygon have 6 faces i.e., a hexagon and as we know mathematically that the angle is 30 degreeSo the radius of circle will be (a / (2*tan(30)))Therefore, r = a√3/2We see the polygon can be divided into N equal triangles. Looking into one of the triangles, we see that the whole angle at the center can be divided into = 360/NSo, angle x = 180/n Now, tan(x) = (a / 2) * r So, r = a / ...
Read MoreArea of Incircle of a Right Angled Triangle in C Program?
To find the area of a circle inside a right angled triangle, we have the formula to find the radius of the right angled triangle, r = ( P + B – H ) / 2.Given the P, B and H are the perpendicular, base and hypotenuse respectively of a right angled triangle.Area of a circle is given by the formula, Area = π*r2where π = 22 / 7 or 3.14 and r is the radius of the circle.Hence the area of the incircle will be given by the formula, Area = π* ((P + B – H) / 2)2.Example#include ...

PL/SQL stands for “Procedural Language extension to SQL” . It is the mixture of SQL and Procedural features provided by programming language. It was developed by Oracle Corporation in the late 1980s as procedural extension language for SQL and the Oracle relational database.PL/SQL programs consists of blocks that can be nested and a block structure look likes this −DECLARE -- it contains declaration statements BEGIN -- It contains executable statements EXCEPTIONS -- It contains exception handling statements END;ExampleIn PL/SQL single-line comments begin with double hyphen(--) and Multi-line comments begin with a slash-asterisk ( /* ) and end ...
Read MoreValue of the class attribute node of an element in JavaScript?
Javascript has provided the getAttributeNode() method to find the attribute node with the specified name of an element, as an attribute object. If the attribute does not exist, the return value is null or an empty string ("").syntaxelement.getAttributeNode(attributename);It returns the attribute object representing the specified attribute node ExampleIn the following example, there are two heading tags with different classes. Those tags when accessed by the getAttributeNode() can return the attribute class with which they attached. It works the same as an array. We can access the multiple classes only by providing their index numbers.Live Demo Tutorix Tutorialspoint var elmnt ...
Read MoreHTML DOM console.table() Method
The HTML DOM console.table() method is used to display data in a well organized tabular format. This method can be used to visualize complex arrays or objects. The table is organized in such a way that each element in the array will be a row in the table. It takes two parameters tabledata(compulsory) and tablecolumns(optional).SyntaxFollowing is the syntax for the console.table() method −console.table( tabledata, tablecolumns );Here −Tabledata is a compulsory parameter value. It represents the data to be used in filling the table. It can be of type object or an array.Tablecolumns is an optional parameter value.It is an array ...
Read MoreHTML DOM console.error() Method
The HTML DOM console.error() method is used for writing an error message to the console. This method is very useful for testing and debugging purposes.SyntaxFollowing is the syntax for console.error() method −console.error(console.error(message))Here, message is a JavaScript string or an object. It is a required parameter value.ExampleLet us see an example for the HTML DOM console.error() method − console.error() Method Click the below button to write object as error message on the console ERROR function errMessage(){ var errObj = { Message:"ERROR has been caused", Value:"NEGATIVE"}; console.error(errObj); } Press F12 ...
