I was reading this document :
http://math.kennesaw.edu/~plaval/math4490/rotgen.pdf
Here the author says that from this figure

that we can express $v_{\perp}$ like this :
T (v_{\perp}) = \cos(\theta) v_{\perp} + \sin(\theta) w
I don't understand this part. Can anybody explain how T(v_{\perp}) is \cos(\theta) v_{\perp} + \sin(\theta) w?
