Let R be the set of all real numbers. Consider the following subsets of the plane R x R: S = {(x, y) : y =x + 1 and 0 < x < 2} and T = {(x,y) : x - y is an integer} Then which of the following is true?
T is an equivalence relation but S is not an equivalence relation
Neither S nor T is an equivalence relation
Both S and T are equivalence relation
S is an equivalence relation but T is not an equivalence relation.

\(\lim _{\theta \rightarrow 0} \frac{\sin \sqrt{\theta}}{\sqrt{\sin \theta}} =\lim _{\theta \rightarrow 0}\left(\frac{\sin \sqrt{\theta}}{\sqrt{\theta}} \cdot \frac{\sqrt{\theta}}{\sqrt{\sin \theta}}\right) \)
\(=\lim _{\theta \rightarrow 0} \frac{\sin \sqrt{\theta}}{\sqrt{\theta}} \cdot\left(\lim _{\theta \rightarrow 0} \frac{\sin \sqrt{\theta}}{\theta}\right)^{\frac{1}{2}}=1.1=1

\(\text {Perimeter }=4+2 \sqrt{2}\)
\(a+a+\sqrt{2} =4+2 \sqrt{2} \)
\(2 a+\sqrt{2} a =4+2 \sqrt{2} \)
\(\therefore a =2 \)
\(\text {Equation of line is } \frac{x}{2}+\frac{y}{2}=1\)
\(x+y-2=0\)

\(\mathrm{T}: x-y \text { is an integer } \Rightarrow x \mathrm{R} y\)
\(\text { i) } x-x=0 \text { is an integer }\)
\(\therefore \text { T is reflexive. }\)
\(\text { ii) }(x-y) \text { is an integer } \Rightarrow y-x \text { is also an integer }\)
\(\therefore \mathrm{T} \text { is symmetry }\)
iii) If (x - y)is an integer and y- z is also an integer, by adding
x - z is also an integer.
\(\therefore \mathrm{T} \text { is transitive }\)
Thus, T is an equivalence relation.
\(\mathrm{S}: \mathrm{y}=x+1 \Rightarrow x \mathrm{~S} y\)
\(\text { i) } x=x+1 \Rightarrow x S x \text { is not true. }\)
\(\therefore S \text { is not reflexive. }\)
Hence T is an equivalence relation but S is not an equivalence relation
