In this tutorial the instructor shows how to calculate the sum of reciprocals of complex numbers. If you have to find out the sum of the reciprocals of two complex numbers first you will have to find out the least common multiple of the denominators. To do this multiply the numerator and denominator of the first fraction by the second complex number. Similarly multiply the numerator and denominator of the second fraction by the first complex number. Now you will have two fractions whose denom...

Being circuitous and using ample euphemisms has gotten many a politan elected by the dumb and hated by the knowing. Though embellishing speech is often preferred in jovial presidential debates, mathematicians prefer to cut out the fat and get straight to the point.

In this video tutorial the author shows how to find the perimeter and area of a complex figure. He shows that a complex figure can be subdivided into standard geometric figures. In the current example he divides the complex figure into a rectangle and a triangle. Now he computes the perimeter by adding the three sides of the rectangle and the two sides of the triangle. Similarly he computes the individual areas of the rectangle and the triangle and finally adds then up to find the area of the...

Welcome back, my eager hackers! In recent blogs, I've demonstrated how to grab password hashes remotely using Metasploit's meterpreter and pwdump. Once we have the Windows passwords from the SAM file, we can then crack these hashes using tools such as Cain and Abel.

This series on complex numbers will help you solve equations with the cute variable "i" with ease by multiplying by the conjugate.

In this tutorial the author explains how to compute the area of a complex figure. Now he first defines what a complex figure is by saying that a complex figure is a figure made up of two or more basic shapes. He uses an example to convey his idea and breaks that sample figure into basic squares and rectangles. Now he computes the areas of these individual units separately and finally puts them together to arrive at the final area of the complex figure. If you are looking to compute the area o...

Math has always had the reputation of being nonimaginative, dry, and straight to the point, but mathematicians like to have fun, too! Perhaps that's why they invented imaginary complex numbers dealing with "i."

The 'Kervorkian Complex' achievement is only accessible while playing the Acquaintances Forgotten side quest in Deus Ex: Human Revolution on the Xbox 360. During the dialogue options, you'll need to continue to agree with Brent Radford until he allows you to kill him with morphine--at this point the achievement will unlock.

We don't know about you, but making selections around oddly shaped areas of an image is one of the most frustrating single tasks in Photoshop. Odd shapes are really hard to navigate around by hand and often you can't get a perfect cut. Luckily, this Photoshop tutorial will guide you through how to make complex selections easily in Adobe Photoshop CS5.

How To Filet Crochet - Part 1 We we first heard the term "filet crochet," an image popped up in our minds of chicken fillets from McDonald's, only made from crochet yarn (yes, we were also quite hungry at the time). Well, we'll have to save the yarn foods for another time, because a filet crochet is actually a very complex, difficult crocheting pattern that requires a graph in order to get the stitches right.

The powers of the complex number "i" run their course in a cyclical nature, like annual seasons of "American Idol." Simplify your life - or at least your math class life - by learning how to rewrite the powers of "i" into simple, single variable expressions.

While basic origami allows for the usage of only one sheet of paper, modular origami increases up to many sheets of paper allowing for increasingly complex shapes. This video tutorial shows how to use the Japanese art of modular origami to create a dodecahedron. Start watching and start folding!

The true test of good technical drawing is being able to handle multiple vanishing points and levels of ground at the same time. So rather than just creating a scene on the same uniform plane, you add additional height and width with complex levels.

In this video the instructor shows how to simplify a complex fraction. A complex fraction is a fraction that has fractions in both the numerator and the denominator of the original fraction. Complex fractions can look intimidating but are generally simple to solve, as shown in this video. A fraction is nothing but a division of its numerator and its denominator. So in a complex fraction basically you are dividing two fractions. Now you can turn this division into multiplication by multiplying...

Complex levels are a lot less, well, complex than they sound when you pay attention to this helpful drawing tutorial. The definition of complex levels is basically creating a three dimensional quality to your work with multiple planes and sometimes ground levels.

In this algebra video the instructor shows how to work with complex numbers. When you have a positive number under the square root, you can easily find its value by writing it in the form of product of numbers, and then solving. That is, to find the square root of a positive number, you can find another number which multiplied by itself gives the original number. This new number becomes the square root of the original number. But when you are asked to find out the square root of a negative nu...

This is a great instructional video on education. This educational video teaches you how to simplify a complex fraction with a single fraction on bottom. Let us learn this with an example. Let us assume we have to simplify the complex fraction 5 by x-4 divided by 5-4x by 5. When you simplify this you will get 5-4x over x divided by 5-4x over 5. You will now get 5-4x over x multiplied by 5 over 5-4x. This is equal to 5 over x. This is how we have to simplify a complex fraction with a single fr...

In this tutorial the instructor shows how to simplify complex fractions. A complex fraction is the same as a normal fraction, but has a fraction problem in the numerator and a fraction problem in the denominator. The first thing to do is arrive at a simple fraction both in the numerator and the denominator. To do this take the lcm of the denominators of the fractions in the numerator and simplify it. Similarly do this in the denominator. Now both the numerator and the denominator have a simpl...

Watch this video to learn how to calculate the area inside complex figures--shapes composed of multiple smaller, simpler shapes. The first step is to break the shape into its simpler component shapes. Then, using the information you have about the large shape, find all information you can about the smaller ones: base, height, etc. Next, find the areas of the smaller component shapes. Finally, add the areas of each of the component shapes together to find the area of the complex shape. Now you...
