反三角函数在matlab中怎样定义
3个回答
展开全部
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
