没用的，壁虎的四肢上的爪子被粘在一起了，没活路了。
在对的时间，遇到对的人，那是童话；
在错的时间，遇到对的人，这才是青春。

回复成功，收到1个大米！
1…0&&parseInt(document.getElementById('custompage_down').value)页楼（sinα=0.612）请问α要怎么用科学计算器求出?请问α要怎么用科学计算器求出?救命啊…科学计算器要怎么按,才能将α求出?
sinα=0.612求α的步骤：（在科学计算器上）先打入：0.612,→按 2ndF 键,→sin键,此时再视屏显示的数字,即为α（=arcsin0.612),单位为度.有的计算器上,2ndF键可能为Shift键,无论什麽符号,只要是用来求“反函数”的键都可.
为您推荐：
其他类似问题
sin-1(0.612)=
-1在sin的右上角，一般的科学计算器都应该有这个功能。CASIO的计算器是按SHIFT+sin的。sin-1手写时作arcsin，是sin的反函数，已知sin的值用sin-1（arcsin）可求出原来的角。
先按SHIFT，再按sin就能求arcsin了。
