Boolean algebra is a branch of algebra. Used for dealing with logical expressions, which are composed of variables, logical operators, and constants. In Boolean algebra, variables take only two values, it is represented as 1 or 0, False or true, and off or on. AND, OR, and NOT are the fundamental logical operators in Boolean … Read more
Before understanding anti-logarithms, you should know about logarithms. Many years ago, when the calculator or the computer was not invented, the calculation of larger numbers was too difficult. In 1614 first time Mathematician John Napier introduced Logarithm and to find a logarithm he published the logarithm table. In 1620, the anti-logarithm table was represented by … Read more
In English, a dangling participle is a participle that does not seem to modify anything at all. In this case, the word being modified is either left out of the sentence or is not located close to the modifier in the sentence. Another way to put it is that a dangling participle is a modifier … Read more
Before going to learn about solving quadratic equations, let us recall a few facts about quadratic equations. The word “quadratic” is originated from the word “quad” and its meaning is “square”. It means the quadratic equation has a variable raised to 2 as the greatest power term. The standard form of a quadratic equation is … Read more
Use the slope formula to find the slope of a line given the coordinates of two points on the line. The slope formula is m=(y2-y1)/(x2-x1), or the change in the y values over the change in the x values. The coordinates of the first point represent x1 and y1. The coordinates of the second points … Read more
How to Determine the Domain and Range of an Inverse Trigonometric Function?In this section, you will learn how to find the domain and range of inverse trigonometric functions. To make you understand the domain and range of an inverse trigonometric function, we have given a table that clearly says the domain and range of inverse … Read more
Comparing numbers is a basic concept that we have learned in our primary classes. When we have two numbers or quantities to compare, then we use three basic symbols, they are: Equal to (=) Greater than symbol (>) Less than symbol (<) Let us learn in this article, how to compare two numbers and what sign … Read more
A nonlinear function is most easily described as whatever is not a linear function. Learn what a linear function is and be able to define a nonlinear function; using examples, learn how to distinguish between the two. What are Linear Functions? The easiest way to define a nonlinear function is as a function that is … Read more
The Discriminant When does ax2+bx+c=0 have a real solution? Well, we know how to find the solutions using the quadratic formula: x=−b±√b2−4ac2a. That makes it look like we can always get solutions. However, we can’t always exercise a square root! Sometimes you’ll see a negative number under the radical. A negative under the radical means there is no real … Read more
Relations and Functions are the most essential topics in algebra. Relations and functions – these are the two different words having separate meanings mathematically. You might get confused about their difference. Before we go deeper, let’s understand the variation between both with a simple example. An ordered pair is described as (INPUT, OUTPUT): The relation … Read more
