1.COS(0.5*ARCSIN(-4/5))2.ARCSIN(1/根号10)+ARCSIN1/根号53.ARCSIN(SIN8派/7)4.ARCSIN(SIN4)
求值1.cos[arcsin(-4/5)-arctan(-3/4)]2.sin[1/2arcsin(-12/13)]
arcsin[cos(3/4π)]=
Cos(arcsin(1/4)+arccos(3/4))求解
cos arcsin x 等于多少?
有几道三角函数的问题麻烦做一下,急,200分1.sin(arcsin(π))2.arcsin(cos(0))3.sin^-1(sin(1/2))4.cos^-1(cos(5π/4))第5和6题是让:重写以下没有任何三角比,电脑打的题目如果看不清楚请看图片,谢谢5.tan(cos^-1(x
tan{arcsin[cosπ/4]+arccos[sinπ/3]+arctan√3}
求值:cos[arcsin(-4/5)-arccos(-3/5)]答案是-1
求值cos(arcsin根号5/4) 帮忙做下,要过程.谢谢了!
