Question

find the value of cot 1140 degrees​

Answer 1

Answer:

Convert degree into radian

cot 1140 ° =

$\cot(1140 \times \frac{\pi}{180} )$

$\cot( \frac{19\pi}{2} )$

Now we will divide the above angle

$\cot(9\pi + \frac{\pi}{2} )$

9π is odd so above angle will lie in 3rd quadrant. And in 3rd quadrant cot functions positive.

$\cot( \frac{\pi}{2 } ) = \cot(90)$

cot 90 = 0

So value of

cot 1140 = 0
