Finding Inverse Cosine in Radians
提问by ivesingh
This gives me the answer in degrees but I want the answer in Radians for Inverse Cosine. For example if I pick 0.5 for invCosineVal it will return 60 deg but not sure how I can find the answer in Radians which should be 1.047.
这给了我度数的答案,但我想要反余弦的弧度答案。例如,如果我为 invCosineVal 选择 0.5,它将返回 60 度,但不确定如何在弧度中找到应该为 1.047 的答案。
ans = Math.acos(invCosineVal) * (180/Math.PI);
回答by Ryan S
ans = Math.acos(invCosineVal)
There you go, 180/Math.PI converts it to degrees
好了,180/Math.PI 将其转换为度数
