有用过Math.sin(y)
可是误差更多
不知道哪里出错
有人可以帮我看看吗?
谢谢喔><

2F：推 LPH66:我说啊..你到底要算什麽没说啊@_@ 08/29 20:46
3F：推 fumizuki:何不用 Double 型态呢 08/29 21:15
4F：推 dong2:呃~就是啊~我也用过Double 可是sin(y)的值都怪怪的 08/29 22:39
5F：→ dong2:所以我用了 Math.Sin(y * 0.01745329252) <==这个= = 08/29 22:40
6F：→ dong2:後来y代30进去就差不多了 可是还是不知道原来那样为什麽错|| 08/29 22:41
