The expression $\cos(x)+\sin(x)\over\cos(x)$ can be written as $1 + {(\; )\over(\; )}$. What is the $(\; )\over(\; )$ term?

${{a+b\over a-b}\over a+b} =$

${u+c\over u}-c =$

${x^2-a^2\over x^2+2xa+a^2} =$

${\left(4-(x+h)^2\right)-\left(4-x^2\right)\over h} =$

${1\over r_1}+{1\over r_2}+{1\over r_3} =$

${{1\over x+h}-{1\over x}\over h} =$

${x-2\over x+2}+{x+2\over x-2} =$

${{1\over3}x+{1\over2}\over2x} =$

$3-{r+1\over r^2-1} =$
