Thanks now i understood. Sorry sometimes i am dumb and gets confused with simpler things.

why it is correct to do this ?

Why we are experessing the Vector as addition of cos(θ)v⊥ and sin(θ)w ? Is it the result of 2 vector addition like Vab = Va + Vb?

Any Help?

I am new to this forum. I was reading this document : http://math.kennesaw.edu/~plaval/math4490/rotgen.pdf Here the author says that from this figure http://i.stack.imgur.com/KBw9l.png that we can express $v_{\perp}$ like this : $$T (v_{\perp}) = \cos(\theta) v_{\perp} + \sin(\theta) w$$...
