The ratios we use the most in trigonometry include sine, cosine, tangent, and a few more. You can calculate these ratios using an angle. If we are aware of the ratio values, we may also calculate the angle using inverse trigonometric functions. This lesson will show you how to compute the angle using the tangent value, in radians, using C++'s inverse-tangent (arctan) function. The atan() function The angle is calculated using the atan() technique and the inverse trigonometric tangent function. The C++ standard library contains this function. We must import the cmath library before we can utilize this approach. This ... Read More
Sine, cosine, tangent, and a few more ratios are some of the ones we utilize the most in trigonometry. These ratios can be computed from an angle. However, we can also determine the angle using inverse trigonometric functions if we know the ratio values. In this tutorial, we'll go through how to use C++'s inverse-cosine (arccosine) function to convert a cosine value to an angle in radians. The acos() function The inverse trigonometric cosine function is used to calculate the angle using the acos() method. This function can be found in the C++ standard library. To use this method, we ... Read More
In trigonometry, there are a few ratios that we use the most, sine, cosine, tangent, and some others. From a given angle, these ratios can be calculated. However, if we have the ratio values, we can also calculate the angle using inverse trigonometric functions. In this article, we shall discuss how to get the angle in radian from the sine value through the inverse-sine (arcsine) method in C++. The asin() function The asin() method is used to compute the angle using the inverse trigonometric sine function. This function is present inside the standard library in C++. We need to import ...

Similar to regular trigonometric functions, hyperbolic functions are defined using the hyperbola rather than the circle. In hyperbolic geometry, hyperbolic functions are used to calculate angles and distances. In addition, they are found in the answers to plenty of linear differential equations, cubic equations, etc. For given angle$\theta$. The hyperbolic tangent function tanh$(\theta)$ is like below − $$\mathrm{tanh(x)\:=\:\frac{sinh(x)}{cosh(x)}\:=\:\frac{e^{x}-e^{-x}}{e^{x}+e^{-x}}\:=\:\frac{e^{2x}-1}{e^{2x}+1}}$$ In this article, we shall discuss the techniques to get the value of tanh$(\theta)$ in C++ when the angle is given in the radian unit. The tanh() function This tanh$(\theta)$ The tanh() function from the C++ cmath library is required for operation. ... Read More
A string is a collection of characters that can represent a single word or a whole sentence. Unlike Java there is no need to declare Python strings explicitly we can directly assign string value to a literal. For manipulating and accessing strings, Python include several built in functions and methods. A string is an object of the String class, which contains multiple methods because everything in Python is an object. In this article, we'll look at how to retrieve the minimum alphabetical character from a string in Python. The min() function The most common solution for this problem is to ... Read More
Hyperbolic functions, which are defined using the hyperbola rather than the circle, are comparable to normal trigonometric functions. Hyperbolic functions are used in hyperbolic geometry to compute angles and distances. They also show up in the solutions to a large number of linear differential equations, cubic equations, etc. For given angle$\theta$. The hyperbolic cosine function cosh$(\theta)$ is like below $$\mathrm{cos(x)\:=\:\frac{e^x\:+\:e^{-x}}{2}\:=\:\frac{e^{2x}+1}{2e^x}\:=\:\frac{1+e^{-2x}}{2e^{-x}}}$$ In this article, we shall discuss the techniques to get the value of cosh$(\theta)$ in C++ when the angle is given in the radian unit. The cosh() function This cosh$(\theta)$ operation needs the cosh() function from the cmath package in ... Read More
A string is a group of characters that may be used to represent a single word or an entire phrase. Strings are simple to use in Python since they do not require explicit declaration and may be defined with or without a specifier. Python provides a variety of built in functions and methods for manipulating and accessing strings in the class named string. In this article, we are going to find out how to get the max alphabetical character from the given string in python. The max() function The most used approach for this problem is the max() function from ... Read More
Layout make the web pages look better and arrange the visual elements on web page. It establishes the overall appearance of the web page. The HTML Layouts specifies the arrangement of different components on a web page. There are many HTML elements that defines different section of a web page. Following are the HTML elements used for HTML layout − S.No. Attribute & Description 1 header It specifies a header for a section of the content on the web page. 2 section It represents a section of the content on web page. ...

A string is a collection of characters that can represent a single word or a whole sentence. Unlike other technologies there is no need to be declared strings in Python explicitly we can define a string with or without the datatype specifier. A string in Python is an object of the String class, which contains multiple methods using which you can manipulate and access strings. In this article we are going to discuss fill out a Python string with spaces. Let’s see various solutions one by one. Using the ljust(), rjust() and center() methods To pad the string with desired ... Read More
Metadata means information about data. The tag in HTML provides complete information about HTML Document. Adding the meta tag while making the webpage or website is a good practice because search engines use this meta tag to understand the information about the website. It is also helpful while searching for a specific website, then the result page will display in search results. These tags are basically used to add author name, value pairs to describe properties of HTML documents, such as expiry date, author name etc. i.e.., it is used to specify a character set, page description and viewport ...
