When we deal with the complex electric circuits (like T-circuits), we use some mathematical techniques to find the current and voltage drops in the circuit. It’s not as difficult as it may seem at the first sight. In this post, we will tell you how to analyze the circuit with the help of the Kirchhoff’s Circuit Law. (more…)
What do you remember about your being 7-year old? A time of enthusiasm and curiosity, new skills and adventures, huh? Well, we dare say that for us, this year has been full of all those above since we’re now seven years old! And we’re excited to share our latest achievements in the field of homework help with you because it’s exactly you who have helped us to become who we are today. So, let’s see how 7-years old Assignment Expert looks like. (more…)
All of us widely use calculators to perform mathematical operations. Obviously, these machines were invented by people, who determined their work according to the certain algorithms for quick count. In this article, we’re going to tell you about one of such algorithms. We’ll also show how you can extract square roots in column and you’ll see that the result of this operation can be received with arbitrary precision; we can find any digits number in its decimal representation, even if it turns irrational. (more…)
Price elasticity is a very important notion in economics, which, however, is not always recognized by students. Let’s imagine that certain firm increases the prices for its products. Many of us may suppose that in this case, the firm has an opportunity to increase the total revenue from the sale of products. But in fact, it doesn’t. It is even possible, that increase in price will lead to the decrease in total revenue because the demand on firm’s product also decreases. That’s why the price elasticity has the great significance for producer of goods and we’re going to tell you how it works in this article. (more…)
Skiing is a good idea to have a good time, especially, in the dead of winter, when a lot of people go to the ski resorts all over the world. But what to do, if the mother nature doesn’t provide us with enough amount of snow to have fun in summer? Or it actually doesn’t bring snow at all. Well, to make an artificial snow, we can use a snow-making equipment, and here we’re going to tell you how it works and disclose the secret of difference between the natural snow and the artificial one. (more…)
Quite often students have some problems with understanding the concept of the vector space basis, the linear dependence and linear independence of the vectors. In this article, we’ll try to explain these terms through simple things and examples. If you still don’t know what the vector is or don’t know how to do simple operations with vectors we offer you to watch our introductory video tutorial and then continue reading this article. (more…)
It’s not a surprise that many students have difficulties with the notions of demand and supply. Let’s say, your instructor asks you to plot the demand and supply curves and tell how the increase of taxation affects demand and supply. And what comes to your mind? If nothing really useful, this article will shed light upon these issues. Here, we tell you about how to plot the demand and supply curves and how to correctly analyze them. (more…)
