【解析】 因为f()处处连续, 故由函数连续的充要条件可得, f(0)=lim_(x/to0)f(x)=lim_(x→0)f(x) . 0 0- 利用洛必达法则计算可得, lim_(x→0)f(x)=lim_(x→0)(cos2x-cosx)/(x^2)= lim_(x→0)(-2sin2x+sinx)/(2x)=-2lim_(x→0)(sin2x)/(2x)+1/2 lim_(x→...

1-cos2x = 2sin²x sin²x ~ x² (x趋于0) 将第二条等式代入第一条等式,便得到: $$1-cos2x \sim 2x² (x \to 0)$$ 这就是为什么1-cos2x的等价无穷小替换是2x²。 总结 通过公式推导和无穷小等价替换,我们可以理解为什么1-cos2x的等价无穷小替换是2x²。这个替换方法在求解极限问题时...
