consider a triangle with known sides a=0.5, b=2, and c=0.5, how could i use law of cosine to find an unknown angle between sides a and b, i tried to use law of cosine it gave me cos(ab)=2, which is impossible

This is an impossible triangle. It does not conform to the triangle inequality!

The Cosine Rule states that
.
In your case, .
So by the Cosine Rule...
.
You are correct, this equation can not be solved. That means that this triangle does not exist... This is easily verified by the triangle inequality...
