Write 'True' or 'False' and justify your answer in each of the following:
$ \frac{\tan 47^{\circ}}{\cot 43^{\circ}}=1 $
Given:
\( \frac{\tan 47^{\circ}}{\cot 43^{\circ}}=1 \)
To do:
We have to find whether the given statement is true or false.
Solution:
We know that,
$\tan (90^o-\theta)=\cot \theta$
Therefore,
$\frac{\tan 47^{\circ}}{\cot 43^{\circ}}=\frac{\tan(90^{\circ}-43^{\circ})}{\cot 43^{\circ}}$
$=\frac{\cot 43^{\circ}}{\cot 43^{\circ}}$
$=1$
The given statement is true.
