1.in a right triangle, the measurement of an acute angle that is equal to the length of the side that is opposite the angle pided by the length of the hypotenuse
1.As a result, I can calculate hyperbolic sines on my 68HC11, but I can't get the performance boost that comes from using just a 24-bit float.
因此，我可以在68HC11计算双曲线，但我不能得到的性能提升，因为仅使用了24位浮点。
2.America sines as "the land of opportunity" , not the land of handouts.
美国一向被诩为“机遇之地”，而不是救济之地。

5.Now, suppose you want to do something as simple as write out the sines of those angles.
现在，假设您想进行一些简单的处理，比如写出这些角度的正弦值。
6.Virtually all the problems were straightforward numerical calculations, such as grinding out tables of sines, cosines, and logarithms .
事实上，所有的问题都是直接的数值计算，比如取正弦、余弦和对数计算。
7.Maybe it will be easier to set up bounds but maybe the function will become harder because it will have all these sines and cosines in it.
可能是积分边界容易确定，但函数可能就比较困难，因为它含有这些sin，cos在里面。
8.I hear some cosines. I hear some sines.
我还听到了余弦，还有正弦。
