Question

$f(x) = \sqrt{x - x^{2}} + \sqrt{4 + x} + \sqrt{4 - x}\lbrack - 4,\infty)$ equals –

Answer 1

Solution

$\lim _ { n \rightarrow \infty }$ $\left[ \frac { 1 } { 2 } - \frac { 1 } { 3 } + \frac { 1 } { 3 } - \frac { 1 } { 4 } + \ldots + \frac { 1 } { \mathrm { n } } - \frac { 1 } { \mathrm { n } + 1 } \right]$ ⇒ $\frac { 1 } { 2 }$
