( 8>f(x)=ln left(1+x^{2}right) ) st symmetic drout youris as ( +f(x)=f(x) ) ( 10 rightarrow quad f(x)=|ln | x|| quad ) symmutic about yaris as ( f(x)=f(-x) ) Also the grabh, bend up alvout ( x=1 ) as ( ln x ) changys stan ( |ln 0| rightarrow+infty ) 11.1 [ begin{aligned} f(x) &=frac{sin x}{sqrt{1+tan ^{2} x}}+frac{cos x}{sqrt{1+cot ^{2} x}} &=operatorname{sen} x+frac{cos x}{cos x} &=sec x &=sin 2 x end{aligned} ]
