化简:sin(540度-X)/tan(900度-X)*1/tan(450度-x)tan(810度-x)*cos(360度-x)/sin(-x)
化简:sin(540度-X)/tan(900度-X)*1/tan(450度-x)tan(810度-x)*cos(360度-x)/sin(-x)
题目的运算有点看不明白,不过下面的化简应该能帮到你的,对号入座就可以了~
sin(540度-X)=sin(180°-X)=sinX
tan(900度-X)=tan(180°-X)= -tanX= -sinX/cosX
tan(450度-x)=tan(90°-X)=cosX/sinX
tan(810度-x)=tan(90°-X)=cosX/sinX
cos(360度-x)=cosX
sin(-x)=-sinX
化简:sin(540度-X)/tan(900度-X)*1/tan(450度-x)tan(810度-x)*cos(360度-x)/sin(-x)
