Consider the rectangles lying the region

$$\left\{ {(x,y) \in R \times R:0\, \le \,x\, \le \,{\pi \over 2}} \right.$$ and $$\left. {0\, \le \,y\, \le \,2\sin (2x)} \right\}$$

and having one side on the X-axis. The area of the rectangle which has the maximum perimeter among all such rectangles, is

$$\left\{ {(x,y) \in R \times R:0\, \le \,x\, \le \,{\pi \over 2}} \right.$$ and $$\left. {0\, \le \,y\, \le \,2\sin (2x)} \right\}$$

By approximately matching the information given in the three columns of the following table.

Let f(x) = x + log

Column 1 contains information about zeroes of f(x), f'(x) and f"(x).

Column 2 contains information about the limiting behaviour of f(x), f'(x) and f"(x) at infinity.

Column 3 contains information about increasing/decreasing nature of f(x) and f'(x).

Let f(x) = x + log

_{e}x $$-$$ x log_{e}x, x$$ \in $$(0, $$\infty $$)Column 1 contains information about zeroes of f(x), f'(x) and f"(x).

Column 2 contains information about the limiting behaviour of f(x), f'(x) and f"(x) at infinity.

Column 3 contains information about increasing/decreasing nature of f(x) and f'(x).

(i) | f(x) = 0 for some $$x \in (1,{e^2})$$ | (i) $$\mathop {\lim }\limits_{x \to \infty } \,f(x) = 0$$ | f is increasing in (0, 1) |

(ii) | f'(x) = 0 for some $$x \in (1,e)$$ | $$\mathop {\lim }\limits_{x \to \infty } \,f(x) = - \infty $$ | f is decreasing in (e, $${e^2}$$) |

(iii) | f'(x) = 0 for some $$x \in (0,1)$$ | $$\mathop {\lim }\limits_{x \to \infty } \,f'(x) = - \infty $$ | f' is increasing in (0, 1) |

(iv) | f'(x) = 0 for some $$x \in (1,e)$$ | $$\mathop {\lim }\limits_{x \to \infty } \,f'(x) = 0$$ | f' is decreasing in (e, $${e^2}$$) |
