Answer 1

I am new to this app please tell me the formula then I I will tell you the answer

Answer 2

Answer:

Cosec (-1410)

Cosec is the reciprocal of the sin so

Cosec(-1410)= 1/ sin(-1410)

Here total angel is -1410. Minus shows that the angle is taken in clockwise direction.

One revolution = 360 degree

2 revolution = 720 degree

3 revolution = 1080 degree

4 revolution = 1440 degree

Sin is 0 for (0,180,360,540,720, so on) degrees

Here degree is -1410

-1410 = - (3 revolution + 330 degree)

sin(-1410) = sin(-1080) + sin(-330)

sin(-1080)=0, because it is like 360 degree

sin(-330) = sin(30)

If we move clockwise from +x-axis 330 degree the other angle anticlockwise from +axis will left 30 degree that's why sin(-330)=sin30

Sin 30 = 0.5

Cosec(-1410)= 1/0.5= 2 answer
