Sir but 4, -4, 2will not be direction ratios as they don't satisfy the condition

[aks]

thank you very much sir 
for uploading new videos.

[shivg]

Thanks a lot
But aap sare theories ko mix kar dete hai
I insist you that
Koi bhi theory complete ho to uske related problems karvaye
For example
There is confusion how to find direction cosine
Please explain both separately
