Answer:
D
Explanation:
A sin 2.355/2.355 =0.01745240644 cos -2.355/2.355 root square
=180 so untrue not-1
B. sin =0.01745240644 cos = 0 so untrue not 1.
C sin = 0.01745240644 cos = 180 so untrue not 1
D = - 2.355/2.355= 0.01745240644 cos = 0.01745240644 = -1 so true.
As if we divide 1 into -1 = 1
When we divide 0.01745240644 / 0.01745240644 = will also = 1
The answer is -1 as inverse.
