The given inverse trigonometric function is
tan {tex}\left[ 2 \tan ^ { - 1 } (\frac { 1 } { 5 } )\right]{/tex}
Now, {tex}\tan \left( 2 \tan ^ { - 1 } \frac { 1 } { 5 } \right) = \tan \left[ \tan ^ { - 1 } \left( \frac { 2 \times \frac { 1 } { 5 } } { 1 - \left( \frac { 1 } { 5 } \right) ^ { 2 } } \right) \right]{/tex}
{tex}\left[ \because 2 \tan ^ { - 1 } x = \tan ^ { - 1 } \left( \frac { 2 x } { 1 - x ^ { 2 } } \right) ; - 1 < x < 1 \right]{/tex}
{tex}= \tan \left[ \tan ^ { - 1 } \left( \frac { 2 \times 5 } { 24 } \right) \right] = \tan \left[ \tan ^ { - 1 } \left( \frac { 5 } { 12 } \right) \right] = \frac { 5 } { 12 }{/tex}
{tex}\left[ \because \tan \left( \tan ^ { - 1 } x \right) = x ; \forall x \in R \right]{/tex}

In flowering plants, pollen grains are formed with the anther. If you look at the diagram to the right, you will see that the anther is a part of the stamen. Essentially, the anther is where the pollen grains are produced! Pollen can be used to determine pollination mechanisms, foraging resources, migration routes and source zones of insects and other pollinators.
