曹齿13662487097：asin&+bcos&=根号(a平方+b平方)sin(&+*)那么asin& - bcos&=? - asin&+bcos&=? -
符富 ...... [答案] asin&-bcos& =-[asin(-&)+bcos(-&)] -asin&+bcos& =asin(-&)+bcos(-&) 然后利用公式就可以了!

曹齿13662487097：asinA+bsinB+csinC=0,acosA+bcosB+ccosC=0求证:a/sin(B - C)=b/sin(C - A)=c/sin(A - B)abc不一定是正数 -
符富 ...... [答案] 由asinA+bsinB+csinC=0,acosA+bcosB+ccosC=0 得到:asinA+bsinB=-csinC,acosA+bcosB=-ccosC 将上面两个式子平方: a^2(sinA)^2+2absinAsinB+b^2(sinB)^2=c^2(sinC)^2 a^2(cosA)^2+2abcosAcosB+b^2(cosB)^2=c^2(cosC)^2 将上面...
