传奇SF架设如何防止攻击

sinacosb=(1/2)(sin(a b) sin(a-b)) cosasinb=(1/2)(sin(a b)-sin(a-b)) cosacosb=(1/2)(cos(a b) cos(a-b)) sinasinb=-(1/2)(cos(a b)-cos(a-b)) 三倍角公式 sin3a=3sina-4(sina)^3 cos3a=4(cosa)^3-3cosa tg3a=[3tga-(tga)^3]/[1-3(tga)^3] 1.诱导公式 sin(-a)=-sin(a) cos(-a)=cos(a) sin(π/2-a)=cos(a) cos(π/2-a)=sin(a) sin(π/2 a)=cos(a) cos(π/2 a)=-sin(a) sin(π-a)=sin(a) cos(π-a)=-cos(a) sin(π a)=-sin(a) cos(π a)=-cos(a) 2.两角和与差的三角函数 sin(a b)=sin(a)cos(b) cos(α)sin(b) cos(a b)=cos(a)cos(b)-sin(a)sin(b) sin(a-b)=sin(a)cos(b)-cos(a)sin(b) cos(a-b)=cos(a)cos(b) sin(a)sin(b) tan(a b)=tan(a) tan(b)/1-tan(a)tan(b) tan(a-b)=tan(a)-tan(b)/1 tan(a)tan(b) 3.和差化积公式 sin(a) sin(b)=2sin(a b2)cos(a-b2) sin(a)?sin(b)=2cos(a b2)sin(a-b2) cos(a) cos(b)=2cos(a b2)cos(a-b2) cos(a)-cos(b)=-2sin(a b2)sin(a-b2) 4.二倍角公式 sin(2a)=2sin(a)cos(b) cos(2a)=cos2(a)-sin2(a)=2cos2(a)-1=1-2sin2(a) 5.半角公式 sin2(a2)=1-cos(a)2 cos2(a2)=1 cos(a)2 tan(a2)=1-cos(a)sin(a)=sina1 cos(a) 6.万能公式 sin(a)=2tan(a2)1 tan2(a2) cos(a)=1-tan2(a2)1 tan2(a2) tan(a)=2tan(a2)1-tan2(a2) 7.其它公式(推导出来的 ) a?sin(a) b?cos(a)=a2 b2sin(a c) 其中 tan(c)=ba a?sin(a) b?cos(a)=a2 b2cos(a-c) 其中 tan(c)=ab 1 sin(a)=(sin(a2) cos(a2))2 1-sin(a)=(sin(a2)-cos(a2))2
