Today I thought I would look at adding and subtracting when using angles, especially when using degrees, minutes and Seconds.
Students so often forget that when dealing with angles you need to add and subtract using time or 60, i.e. 60 min and 60 Seconds.
The small slide set I made in Google Docs is all I need to show this, plus some easily worked examples similar to the video that I have embedded into the slide presentation.
For me when I was putting this together I thought this is excellent CPD and made a note to included it here to remind you all about the way it’s done, adding is the easy side, but its the subtraction that so often get them, particularly if the lower angle is in part, larger part. You just have to remember to transfer from the a degree 1 minute and also to lower the minute, watch the video its self explanatory.
I have also included a small video below that shows how I get the html code of my google Doc presentation and embed it into the code of this blog, so similar to adding it to the Moodle notes section.
The photo I used today I took on my trip to Lullworth Cove and is of a very fine old brick Arch in one of the market towns, shallow and wide it has stood the test of time and works.
My use of Google Docs is known, I write there, and use the spreadsheet to keep my CPD records, so when I saw this excellent little video on YouTube I thought neat, perhaps I should spend a little time and catch up on some of the commands.
First though take a look at this web site and see the code in action, then scroll down and watch the video, it shows such a great way to import data from tables in web sites and there are many.
It's has made me sit and think, what else can I use it for, so in the future I will let you know.
