when i made a point: 5cos40 + 5isin40
I got the point (3.86,3.18)
with mine calculator i got:(3.83,3.21)
who is more right?
Point C is just an arbitrary point on your circle, you can drag it without changing alfa.
You need to construct the point so that it is on the circle, i.e. C = ( a cos(alfa), a sin(alfa) )
the problem is that geogebra gives diffrent answer than mine calculator (casio).
well, imoved the point a littie, and now it's o.k.
