lim x→0 (1-cosx√cos2x√cos3x)/(e^x+1)sinx dx
lim(x→0)(cos2x-cos3x)/{[(1+x^2)^1/2]-1}
lim(x→0)(cos2x-cos3x)/{[(1+x^2)^1/2]-1}
lim x趋于零 cos2x减cos3x
求极限 lim(x→0){(cos2x-cos3x)/[(1+x^2)-1]}打错了。应该是lim(x→0)(cos2x-cos3x)/{[(1+x^2)^1/2]-1}

lim(x→0)(1-cos2x)/xsinx
高数极限x→0时2/3 lim cos2x/cos3x limsin3x/sin2x=1是怎么计算的?使用洛比达法则。原题目是求x→0时lim ln(sin2x)/ln(sin3x)的极限?
请问lim x→0 (cosx-cos3x)/x的平方等于?lim x→0 (cosx-cos3x)/x的平方请写好步骤!

lim(cosx+cos2x+ cos3x+…+ cos nx-n)/(cosx-1) (x趋于0)2,3,n之类的是幂,不是2乘以x
求lim x→0 (tan2x-sinx)/x以及lim x→0 (cosx-cos3x)/x^2
