The sum of all angels of a polygon is 1080°. How many  sides does  the polygon have?  [M-1.5, IUT : 2021-22]

$\dfrac{\cos A}{1-\tan A} + \dfrac{\sin A}{1 - \cot A}$is equal to

If $\tan\theta=\dfrac{3}{4}$ and $0< \theta, < 90^0,$ then the value of $\sin\theta \cos \theta$ is

Evaluate

$\displaystyle \frac { \tan { A } +\sec { A } -1 }{ \tan { A } -\sec { A } +1 } ;$

Which of the following is / are the value (S) of the expression?

sin A(1+ tan A) + cos A (1+ cot A) ?

1. sec A + cosec A

2. 2 cosec A ( sin A + cos A )

3. tan A + cot A ;
