Cos and sin. Awsome

Hello,

I was wondering if someone could briefly explain cos and sin and what they do. I was also wondering what are some cool equations they are usable in.

Thanks

    @socks has given some awesome demos in the past. at it's most basic it can be used to orbit a point. you can also use it to do some crazy stuff with rotation/waves and more.

    I threw together a quick video explaining very briefly what they do and demonstrating their use. I have an "Illustrated Guide to Sine and Cosine" planned but this is a quick intro until then.

    Hopefully it makes sense, I didn't watch it after recording it, just chopped out some frames that would have had me breaking NDAs...

    @Armelline Nice! Really looking forward to the sin & cos guide.

    @Armelline Great video, but the sound is really quiet. :)

    I think I bugged him too much about it.

    Great! Thanks!> @Armelline said:

    Thanks so much. Those are REALLY cool.

    I just got a game idea with the waves he showed me! Thanks guys!

    Cosine and sine don't do anything, asking what cos and sin do is like asking what West and North do !

    If you have a circle - and you draw a line from the centre to the edge, at whatever angle you like, we call the horizontal distance from the centre of the circle to the end point of that angle the 'cosine' of that angle, and we call the vertical distance from the centre of the circle to the end point of that angle the 'sine' of that angle.

    Here's a good gif of how @Sock's information about circles translates to the practical uses in GameSalad in my video:

    @Armelline Wow Nice find! Or did you make that yourself?

    @Socks This is why we love you Socks.

    Trig was never my strong point in high school, good thing I'm not in a mathematics major... I was always in advanced or elevated math classes, but when the dreaded Trig unit came I was always totally screwed for that unit. :smiley: :blush: Ahhh High School.

    @Armelline Great video man!

    Just something I saw one time that Google found again swiftly for me!

    Well, that shows my skill in it. Thanks for clearing that up :)
