已知sin(a+π/3)+sina=-4根号3/5 -π/2
已知sin(a+π/3)+sina=-4根号3/5 -π/2
已知sin(a+π/3)+sina=-4根号3/5 -π/2
(3*根号3-4)/10
已知sin(π+a)=1/3,则sina=
已知tan{π/4+a}=3,求sina*sin(3π /2 +a)-sin^2a+1的值
已知sina=1/3,则sin(a+π/4)cos(a+π/4)
已知sin(a+π/3)+sina=-4√3/5,-π/2
已知sin(a+π/3)+sina=-(4倍根号下3)/5,-π/2
已知sin(a+π/3)+sina=-4√3/5,-π/2
已知sin(a+π/3)+sina=-4根号3/5,-π/2
已知sin(a+π/3)+sina=-4根号3/5 -π/2
已知tan(π-a)=2,求值:(1)2sin+2cosa/7sina+cosa(2)sina*cosa(3)4cosa^2+3sina^2
已知(sina+cosa)/(sina-cosa)=3 则2sin'a+(sina-cosa)'=?
已知sin(a+kpai)=-2cos(a+kpai)(k属于z)求(4sina-2sina)/(5sina=3sina)1.(4sina-2sina)/(5sina=3sina)2.0.25sin^2 a+0.4cos^2 a在线等,需要过程,有答案了会加分求(4sina-2cosa)/(5cosa+3sina) 之前打错
已知sina+sin^2a=1,求3cos^2a+cos^4a-2sina+1
已知sin=-3/5,那么(cosa+sina/cosa-sina)+(cosa-sina/cosa+sina)(a代表角,
已知向量a=(3sin,cosa),b=(2sina,5sina-4cosa),a属于(3π/2,2),且a垂直b,求tana值
已知sina=-1/3 则sin(a+x)=
已知锐角A满足关系式4sin平方A-8sinA+3=0,则sinA值为
已知tan a =-1/3,求sina-2cosa/3sina+4cosa和sin^2a-3sin a cos a +2的值.
已知sin(2π-a)=4/5,a∈(3/2π,2π),则(sina+cosa)/(sina-cosa)等于
