化简1.sin(a+p)cosa-cos(a+p)sina 2.sin(a-p)cosp+cos(a-p)sinp
化简1.sin(a+p)cosa-cos(a+p)sina 2.sin(a-p)cosp+cos(a-p)sinp
化简1.sin(a+p)cosa-cos(a+p)sina 2.sin(a-p)cosp+cos(a-p)sinp
.sin(a+p)cosa-cos(a+p)sina=sin(a+p-a)=sin(p )
sin(a-p)cosp+cos(a-p)sinp=sin(a-p+p)=sin(a)
化简1.sin(a+p)cosa-cos(a+p)sina 2.sin(a-p)cosp+cos(a-p)sinp
化简1.sin(a+p)cosa-cos(a+p)sina 2.sin(a-p)cosp+cos(a-p)sinp 请问你能帮我解答下
sin(a-p)cosa-cos(p-a)sina=3/5sin(a-p)cosa+cos(a-p))sina=3/5
化简1.(sina-cosa)² 2.sin a/2cos a/2 3.cos四次方a -sin四次方a 4.1/1-tana -1/1+tana
设a是第二象限角,则点p(sin(cosa),cos(cosa))在第几象限,
化简sin(a-b)*cosa - cos(a-b)*sina
Sin^4a+Sina*Cosa+Cos^2a化简
化简:(sina+cosa)2一2sin a cos a
化简sin(a+30)+cos(a+60)/2cosa
若a是第二象限角,则点P(sin(cosa),cos(sina))是第几象限呢?
设a是第二象限角,则点P(sin(cosa),cos(sina))在第几象限
(1+sina+cosa)(sin(a/2)-cos(a/2))/根号(2+2cosa)化简 (0<a<π)-cosa
设a是第二象限角,则点P(sin(cosa),cos(sina))在第几象限
化简(1+sina+cosa)[sin(a/2)-cos(a/2)]/根号(2+2cosa) (0°
sina+cosa/sina-cosa=3,计算1/(sin²a-sinacosa-cos²a)
化简sina^8-cosa^8-sin^6a+cos^6a+sin^4a
求证:sin(a+β)sin(a-β)=(cosβ)^2-(cosa)^2
cos(a+60度)cosa - sin(a+60度)sin等于多少?
