Thanks Arne, I have been looking for a YT video to show me how to create a unit circle for getting all the trig values. Your video has been very helpful. Thanks.

You are a blessing to this world.......Thank u thank u...
U won't understand what this video means to me....pls I insist to cintinue making such videos

I was able to reproduce the unit circle with your video. Thank you very much. This helps a lot!

Thanks, hope it made trigonometry easyer. :-)

Awesome! Just a quick question... How can I make a line from B parallel to the horizontal axes?

[@ArneTerpAndersen]

Thank you. The tool i use at 2:15 the "perpendicular line" is perfect for the task using the y-axis. Alternatively there is a "parallel line" tool in the same groupe of tools. Both make relative lines to an other line/axis and a point.

Really good video!

Great video Arne! By the way, is the calculator part of GeoGebra? If so, where do I get it? I know there is a calculator in the GeoGebra Maths but I can't find any in the GeoGebra software! Thanks!
