Well assuming X for both values started at the cos 1 and sin 1 you would end up at the cos-1 and sin -1. Angle of 270
Cos = 1, sin = 1 is a position outside of the circle, image a square with the same width and height as the circle, then cos = 1, sin = 1 would be the upper righthand corner.
It's the same for 'cos-1 and sin -1' - this describes a point outside the circle.
Also, values don't 'start at' anywhere, they are just what the are, a value or coordinates doesn't have a 'start' ?
@Thunder_Child said:
No wait. It would meet at 0,0 but if continued go to 270
Not sure what 'meet at' means, like I say, these are just coordinates, so the coordinate 4,2 doesn't start out somewhere else or meet at another location, it simply is 4,2.
It's much simpler than people tend to want to make it.
Like I say, I'm not sure what 'meet at' means or why your angle is now 225 ? Nothing is meeting or ending anywhere ?
If I were to tell you that a well can be found on a map at x=221, y=302 . . . then where would you say this meets or ends at, and what is it that is ending ?
Just go back and check your values. Angle = 260 is right, but cos=.4 sin=.9 is wrong. Any further mistakes will be met with deadly force.

Assuming you are talking about where they woukd be intersecting the "cirkel"
Yes, where your angle intersects the circle gives you the cos (the horizontal distance from the centre) and the sin (the vertical distance from the centre).
@Thunder_Child said:
I was assuming you were wanting to know where the coordinates with intersect the circle.
Yes, the cosine (cos) of an angle is where horizontally that angle intersects the circle - and the sine (sin) of an angle is where vertically that angle intersects the circle.
Oh ok yes I see the error of my ways. I really appreciate the time to help us in this "class".
Im going to scour through and grab all the good stuff and make a new note page for it. Do some more "practices".
You said a new world of stuff could open up learning just this. My goal is to make my own version of a planet orbiting a star. Self test.
Of course ultimately look through your video and try to mimic the reels action...which was my ultimate goal of this thread. :-)
Well, this 'class' has turned into a mess it's now full of erroneous drawings with arbitrary values scrawled all over them, -0.7, .7, 0.7 all seem to be used interchangeably, we even have a circle with -7 indicated on it, Lol, that's 7 times the size of our circle, and on the circle where 0.9 is used in place of -0.9 the circle shows -9 (nine times the size of our circle as well as being positive rather than negative) as well as a load of strange (and irrelevant) concepts like coordinates starting at one position and moving to other positions, arrows on angles indicating something I'm not entirely sure about, my favourite though is 'they would meet at 0 and end at 225*', which seems to be about an angle as 225 seems too far outside of a circle with a radius of 1 even for this rowdy class, but then it can't be a comment about an angle as it refers to 'they', meaning more than one, and again the idea of something 'meeting' and then 'ending' is introduced, I now strongly suspect 'they would meet' refers to a group of tiny woodland creatures led by an evil owl, but I can't be sure anymore. Anyone reading this thread would be very confused working through all this stuff. And no one has moved beyond Lesson 6 (Lesson 7 is still unanswered)!
So classed dismissed !! Your parents will be informed of your poor behaviour, as will the local secret police, expect a knock on the door late at night.
Well I apprciate the chance to learn something. Ill do what I can to learn more of the basics...and try to remove the image ruin of Sharon Stone having ever been a man.

They woukd meet at 0...then end at 225*
Cos -.7
Sin-.7

Ok. I was putting too much into it I was assuming you were wanting to know where the coordinates with intersect the circle.
So is my answer correct or is it -1 -1 outside of the circle

The image with .4,.9 was just practice. That was not an answer to your pop quiz.

Yes, the cosine (cos) of an angle is where horizontally that angle intersects the circle - and the sine (sin) of an angle is where vertically that angle intersects the circle.
No, your answer was wrong, the correct answer was -0.4, -0.9 (you gave 0.4, 0.9 as your answer). This is all going on your end of term report.
Lol
ok, it was just 'practice' (but it was still wrong 
).

What? Wait!
Hey 'teacher' thanks to @Lovejoy, everyone was getting used to thinking of you like this:
Now you tell us you've had an operation. Then you dismiss the class without a conclusion!
I suppose we'll soon find out the operation resulted in this:
As expensive as it was I couldn't continue living a lie, so I paid £30 to the man with the hammer and the stapler . . . and gritted my teeth.
I'm not just dismissing the class, I'm having them rounded up in the middle of the night and dragged off to the trigonometry labour camps.
Well I apprciate the chance to learn something. Ill do what I can to learn more of the basics...and try to remove the image ruin of Sharon Stone having ever been a man.
