are these right !

Yes they are correct. I've never seen them written on a unit circle backward before but they are right.

All looks good to me.

Remember. If you take any point on the unit circle, cos will be the x value and sin will be the y value

It is easy to see why this is true because the hypotenuse is one.

what about the coordinates in the second graph !

the place which I put in question mark ?
