The tag in HTML is used to mark a text that is no longer relevant. This tag was redefined in HTML5 to display a text that is not accurate.Let’s see an example to implement the element −Example Live Demo Exam Results Result would be announced on 6th June. New date for results are 7th June. OutputIn the above example, we have set a text which is no longer relevant− Result would be announced on 6th June. The usage of would strike the same text as shown in the above output.
The cite attribute of the element is used to set the source URL of a quote. The source won’t get displayed on the web page, but it is beneficial for the screen readers.Let us now see an example to implement the cite attribute of the element −Example Live Demo What we want? PETA states, We are the largest animal rights organization in the world, with more than 6.5 million members and supporters worldwide.

Definition and UsageThe acosh() function returns the inverse hyperbolic cosine ratio of given angle in of given parameter. In other words, the return value of asinh() is hyperbolic sine of given parameter. A hyperbolic inverse hyperbolic cosine function is defined as −.acosh(x) = log(x+sqrt(pow(x, 2)-1))This function returns a float value.Syntaxacosh ( float $arg ) : floatParametersSr.NoParameter & Description1argA floating point value whose inverse hyperbolic cosine is to be calculatedReturn ValuesPHP acosh() function returns inverse hyperbolic cosine ratio of given parameter.PHP VersionThis function is available in PHP versions 4.x, PHP 5.x as well as PHP 7.x.ExampleFollowing example calculates acosh(pi/2) and returns ...

Definition and UsageThe acos() function Returns the arc cosine or cos inverse of arg in radians. acos() is the inverse function of cos(). Therefore if cos(x)=y, acos(y)=x.For example, cos(pi/2)=0 and acos(0)=1.57079633 rad which is equal to pi/2.This function returns a float value.Syntaxacos ( float $arg ) : floatParametersSr.NoParameter & Description1argA floating point number whose arc cosine is to be calculated. Number should be withing -1 to 1Return ValuesPHP acos() function returns arc cosine of given number. It is angle represented in radians.PHP VersionThis function is available in PHP versions 4.x, PHP 5.x as well as PHP 7.x.Example Live DemoFollowing example calculates ... Read More
Definition and UsageThe abs() function is an in-built function in PHP iterpreter. This function accepts any number as argument and returns a positive value, disregarding its sign. Absolute value of any number is always positive.This function always returns positive number.Syntaxabs( mixed $num)ParametersSr.NoParameter & Description1numThis parameter stores a value whose absolute value is to be obtained.Return ValuesPHP abs() function returns absolute value of num. If data type of num is float, return type is also float.For integer parameter, return type is integer.PHP VersionThis function is available in PHP versions 4.x, PHP 5.x as well as PHP 7.x.Example Live DemoFollowing example shows that ...

We can perform right click on an element in Selenium with the help of Actions. In order to perform the right click action we will use contextClick () method. First we need to move to the specific element with the help of moveToElement() method then will do the right click with contextClick() method. Finally use build().perform() to execute all the steps.Exampleimport org.openqa.selenium.By; import org.openqa.selenium.Keys; import org.openqa.selenium.WebDriver; import org.openqa.selenium.WebElement; import org.openqa.selenium.chrome.ChromeDriver; import org.openqa.selenium.interactions.Action; import org.openqa.selenium.interactions.Actions; import java.util.concurrent.TimeUnit; public class RightClick{ public static void main(String[] args) { System.setProperty("webdriver.chrome.driver", "C:\Users\ghs6kor\Desktop\Java\chromedriver.exe"); WebDriver driver = new ChromeDriver(); ...
