Question

Tantita
$\tan( = )$
=​

Answer 1

By the definition of tangent ratio, it is defined as:

$\underline{\sf tan( \theta) = \frac{opposite \: side}{adjacent \: side}}$

$\sf tan( \theta) = \theta + \frac{ { \theta}^{3} }{3} + \frac{2 { \theta}^{5} }{15} + \frac{17 { \theta}^{7} }{315} + ..._{\infin}$

Where, θ is measured in radians.

and,

$| \theta | < \frac{\pi}{2}$
