Formula for Tan(a+b):

$\bold{\boxed{Tan(a + b) = \frac{TanA+ TanB}{1 - TanATanB}}}$

$\bold{ = \frac{ \frac{1}{2} + \frac{1}{3} }{1 - \frac{1}{2} \times \frac{1}{3} }}$

$\bold{ = > \frac{ \frac{3 + 2}{6} }{1 - \frac{1}{6}} }$

$\bold{ = > \frac{ \frac{5}{6} }{ \frac{5}{6} } = \frac{5}{6} \times \frac{6}{5} = 1}$

$\bold{∴\: The\: value \:of \:Tan(a+b)\: is \:1}$

$\huge\mathcal{More\:To\:know}$

$\bold{\boxed{Tan(a - b) = \frac{TanA-TanB}{1 +TanATanB}}}$
