I have just created another video about some basic math. This one is about what is probably the most useful branch of mathematics for practical work, trigonometry. I am not going to bore you here with a repeat of what is in the video, but what I will do here is provide a whole bunch of links that will be very helpful to you.

First, I created a pdf with all the information summarized. If you have trouble remembering the formulas, it is all there.

A Right Triangle Summary That is associated with my earlier post on the same subject: Episode 36 – A Right Triangle and Trigonomety

I have also created a spreadsheet that will do all the work for you. It can be found at: Basic Trig. Spreadsheet. This spreadsheet is in excel format. If you do not have access to spreadsheet software, it works fine in LibreCalc and I highly recommend this free and open source software. it is actually what I use and used to write the spreadsheet. You can find the download and information for LibreOffice at their website: LibreOffice Home Page.

I have also created several posts showing how useful this mathematics is. Two examples are:

The Impedance and Power Triangles & Introduction to Statics and Forces on a Beam. Those last two posts were early in this website’s development and when I was still trying to do this with voice only podcasts. The kind of work I do here requires visual so I no-longer do podcasts except if rare cases.

The most recent video is here:
