Dear visitors of derive-it.com, Derive-It is moving to YouTube under the name, Mastery of Mathematics. On this channel, you will find mathematics tutorials about algebra, precalculus, and calculus. Please check it out and subscribe to see the new videos that appear! I’ll be posting new content every week, at least! Here’s the link: https://www.youtube.com/channel/UCcJbHJfLytnL9HqRRYiMk2g The post Moving to YouTube! appeared first on derive-it.com ..read more

Here you can learn more about real numbers, which include rational and irrational numbers. A real numbers can be plotted on a number line. To learn more, you can watch this YouTube video about real numbers, below. The post Real Numbers appeared first on derive-it.com ..read more

In this post, you will learn how to leverage Python code that has already been written. This reusable code is available in the form of so-called modules and libraries. In what follows, you will learn about modules and libraries, as well as the differences between them. Also, this post contains useful information about the basics of commonly-used libraries and modules. Learning these fundamentals will be helpful later, when concepts are combined to accomplish a task in the field of Data Analytics. What is a module? In Python, a module is reusable code that you can build upon in a Python program ..read more

This post will teach you about computers and show you how to set up a programming language called Python. Operating Systems A computer is characterized by its operator system, or OS for short. The most common operating systems are Windows, Linux/UNIX, and macOS. This guide will focus on Windows and macOS. If you have a macOS computer, for example, you can skip the sections about Windows. What is a terminal? A terminal is an interface that allows you to type commands. The commands that you type depend on what you want the computer to do. Each operating system has its own terminal. When you open ..read more

What does a Data Analyst do? The job responsibilities of a Data Analyst are computer-based, and this work can be done remotely or in-person at the office. There can be meetings throughout the day, such as a quick meeting in the morning to discuss the current projects. It can be helpful to provide consistent updates and to get feedback. The role of a Data Analyst is typically a full-time commitment with responsibilities in the morning and the afternoon. The actual tasks of a Data Analyst involve the analysis of data as well as communication with others to make sure the analysis is done correctl ..read more

Recall the following form of Gauss’s Law from this post: $ \frac{\partial}{\partial x} E_x +  \frac{\partial}{\partial y} E_y + \frac{\partial}{\partial z} E_z = \frac{\rho}{\epsilon_0 \epsilon_r} $ One Dimension If a problem is “one-dimensional” along the, say, $x$-axis, one has $ \frac{\partial}{\partial x} E_x  = \frac{\rho}{\epsilon_0 \epsilon_r} $ In words: the partial derivative with respect to $x$ of the $x$-component of the electric field is equal to the volume charge density divided by $\epsilon_0 \epsilon_r$. In one dimension, sometimes people use a linear charge densi ..read more

Hi All, I am planning on writing blog posts focused on math and physics topics, specifically those that students find challenging in high school and college. So, if you could let me know what you found difficult during your college or high school experience, by emailing me or by leaving a comment on this post, that would be very helpful. Maybe your topic will appear in an upcoming post. Thank you!

Pi, or $\pi$, is commonly used in the context of circles in geometry. In particular, the circumference $C$ of a circle that has a diameter $d$ is $C = \pi d$. Also, the area $A$ of a circle with radius $r$ is $ A = \pi r^2$. Note that $2r = d$. This is how $\pi$ is defined. It is a little weird that $\pi$ is defined in the context of two equations, but that is how we understand what $\pi$ is. Interestingly, $\pi$ is an irrational number, meaning it cannot be written as a ratio of two integers. An approximation of $\pi$ is: $3.1415926535897932384626433832795028841971693993751058209749445923$. T ..read more

What is the Pythagoras theorem? It is $ a^2 + b^2 = c^2$. Here, $a$, $b$ and $c$ are the lengths of a right triangle. Note that $c$ is the hypotenuse of the right triangle. A right triangle has an angle of 90 degrees. The post Pythagoras Theorem appeared first on Christina Daniel ..read more
