Hint : 3sinα+2tanαcotα=3sinαcotα+2tanαcotα But sinαcotα=1cos(α)2cosα and tanαcotα=1cos(α)2cos(α)2

How to evaluate limx055cos(2x)+sin(4x)x without using LHospitals rule?
I thought the best way was to separate it in two limits:
limx0(55cos(2x)x)+limx0(sin(4x)x)
Considering that limx0(sinxx)=1 we can easily know that the second limit is 4. I also know the result of the original limit is 4, so the result of the first limit in the second line needs to be 0 (0+4=4).
The issue is that I can not figure out how to remove the x from the denominator so I can avoid the indeterminate form. I already tried replacing cos(2x) with cos2xsin2x, but it seems to be useless.
So, to summarize everything, my problem is how to evaluate this limit without using LHospitals rule:
limx0(55cos(2x)x)
