1、弧度值反三角函数：
asin（）——反正弦
acos（）——反余弦
atan（）——反正切
acot( )——反余切
2、角度值反三角函数：
asind（）——反正弦
acosd（）——反余弦
atand（）——反正切
acotd( )——反余切
arcsin(x)---->asin(x)
arccos(x)---->acos(x)
arctan(x)---->atan(x)
arccot(x)---->acot(x)
asin（），acos（），atan（），acot( ) 生成的值为弧度值，即rad；
asind（），acosd（），atand（）, acotd( ) 生成的值为角度值；
将弧转换为角度的命令：rad2deg（）
deg2rad（）作用则相反
三角函数和反三角函数定义的Matlab函数名称如下：
正弦sin 反正弦asin
余弦cos 反余弦acos
正切tan 反atan
余切cot 反acot
