Cos(arcsin(1/4)+arccos(3/4))求解
tan{arcsin[cosπ/4]+arccos[sinπ/3]+arctan√3}
反三角函数求值arccos(cos5π/4)=?arctan(tan4π/3)=?arcsin(sin6)=?
4道高数求导求解:y=arccos(1-2x) y=lncot(x/2) y=e的负3分之x次方×sin3x y=cos
Arcsin(cos(90+a))+arccos(sin(180+a)) 若0
arcsin|x|>arccos|x|
sin(x) cos(x) tan(x) cot(x) sec(x) csc(x) arcsin(x) arccos(x
sin cos tan cot arcsin arccos这些是怎么转换呀?
cos(arccos派/3)的值,
1.COS(0.5*ARCSIN(-4/5))
解方程:arccos| (x方-1) /(x方+1)| +arcsin |2x/ (x方+1)| +arccot | (
arctan(-1),arcsin(-1),arccos(-1)分别是多少?拜托了各位 谢谢
计算:arcsin(-根号2/2)-arccos(-1/2)+arctan(-1)-arccos1
