you have attached a transformation, where p' is the transformed vector of p by the rotation matrix that you just showed
as stated above you'll need to understand the maths behind this
you can't just take shots in the dark with this and learn only the basics, because this knowledge is crucial to game development

the matrix shows you a homogenous transformation matrix, a basic rotation around x-axis in a 2D system R2
hence the 3rd column (tx, ty, w), where w is the homogenous coordinate
this isn't something that helpful people on gamedev can explain to you in 1-10 posts
