We are given points \( A = [1,-1,2] \), \( B = [0,5,-3] \), \( S = [2,0,5] \). Point \( S \) is the centre of a parallelogram \( ABCD \). Find the coordinates of vertices \( C \) and \( D \).

Given the graph of the function \( f \), find \( \lim\limits_{x\rightarrow1^+}f(x) \).

Given the graph of the function \( f \), find \( \lim\limits_{x\rightarrow1}f(x) \).

Given the graph of the function \( f \), find \( \lim\limits_{x\rightarrow0}f(x) \). \[f(x)=x^2\cdot\cos\!\left(\frac1x\right)+a,\ a\in\mathbb{R}\]
