- Converting Point Slope Form to Standard Form - When you're learning how to write an equation of a line, there are a couple of different forms that you can use to express it. Learning how to convert from one to another is an essential skill, and this post explains how you can do it.
- Stretching and Compressing Graphs - Coming up with a standard graph of a function isn't too hard. But what about when you are asked to stretch it or compress it, and express what you've done right in the equation of the function. Here's a primer that will show you what to do.
- Which Measure of Central Tendency to Use - When you begin studying statistics, and learn about the various measures of central tendency, there is understandably a confusion in some cases about which measure to use with certain situations. Take a look here at some pointers to help you choose which is best for you to use.
- Graphing Parallel and Perpendicular Lines - Graphing lines is a fairly standard and simple exercise. However, do you know what to do if you're asked to take the line you have, and come up with an equation for a line that is parallel or perpendicular to it? There are a couple of key points to keep in mind for this, and you can find out about them here!
- Special Angles in Trigonometry - It's no secret: trigonometry is one of the most hated topics in mathematics by students. I can't explain where the fear comes from, but I will acknowledge that trig can be confusing - incredibly so, sometimes. Thankfully, there are several shortcuts that take out the heavy work and let us skip several steps. The special angles in trigonometry are one such concept. If you can remember there, then you can miss out on a lot of repetitive and potentially confusing work. Study up on these angles here!
