Rotating a Vector: Proof
In this video I derive the formula for rotating a vector by any specific angle. In the derivation, I utilize the cosine and sine angle addition identities which I had proved in my earlier videos. The concept of rotating vectors is very important in mathematics and physics, so make sure you fully grasp it!
This video was taken from my earlier video listed below:
