How can you calculate the IFFT (Inverse Fast Fourier Transform) using only the forward FFT (Fast Fourier Transform)? It is easier than you think! Read on to find out how.

1. Cheat-Sheet: How?
2. Derivation of the Method

Arguably of the best reasons for getting a calculator with a CAS (computer algebra system) is to solve derivatives, integrals, and summations symbolically. Here's how to do it with the HP 50g.

1. Derivatives
2. Indefinite Integrals
3. Definite Integrals
4. Summations

This is a basic tutorial on managing variables and folders on the HP 50g calculator. Deleting variables is easy once you know what to, but it gives people trouble at the start when learning how to use this calculator. Using folders effectively is important because it helps with organizing variables and lets you have more than one sets of variables or constants saved for different types of problems or classes. The file browser is useful for navigating folders but also good for helping you delete large amounts of variables quickly.

This alarm clock was made for a project in ECE362 at Purdue University, taught by Professor Meyer. The assignment was called a mini-project and our team of three had a little over a week to complete it. The guidelines of the project were very lenient and were to basically to create anything we wanted using the Freescale HS9S12C32 microcontroller, while utilizing at least 4 the following modules: analog to digital (ATD), pulse width modulation (PWM), timing (TIM), serial peripheral interface (SPI), and SCI (UART).

Graphing on the HP 50g took me a while to get used to. You have to go through a few separate menus to create a nice looking graph. This threw me for a loop because I was used to a calculator that had most the options for creating a graph in one place. Here is a little guide that will get you acquainted with the very basics of creating a graph on this calculator. There are three main steps.

1. Entering the function
2. Setting up the tick marks
3. Setting up the window
4. A few tricks

There is a lot of great free software available for download on the internet but sometimes it is hard to find the programs that are really worth downloading. Below is a list of my favorites that I have found over the years and a link to where you can find them.

This guide is meant to teach you the very basics of getting a website online. It assumes that you have already created a website and now want to put it up on the internet for everyone to see. I was in this very situation just recently, but as you can obviously tell, not anymore! This is going to be a very simple and non-technical guide on how to get your website online. I found that most of the guides I found on the internet were either overly complicated, or focused solely on one aspect of the process. This left me searching for guides on the other parts. Now lets get started. The process basically comes down to three steps:

I am in the process of creating this new web page. I am building the website using the Drupal CMS. Updates will be happening periodically when I have time. I am a busy student but I enjoy this so I can usually find time for it :)
