it is 0because on the unit circle 270 is the negative y axis (0,1) the x coordinate is the cos value
The cosine of 90 degrees is zero.
The cosine of 8 degrees is 0.99026806874157031508377486734485
Cosine is 0.766
The cosine of 24 degrees is 0.913
cosine(59 degrees) = 0.51504 (rounded)
Firstly, with the unit circle (r=1) we need to know that:at 270 degrees our coordinates are (0, -1)sine(270 degrees) = -1cosine(250 degrees) = 0cotangent = cosine / sinetherefore: cot ( 270 degrees) = 0/-1 = 0The answer is 0.
The cosine of 90 degrees is zero.
The cosine of 8 degrees is 0.99026806874157031508377486734485
For an angle of 90 or 270 degrees. In radians, pi / 2 and 3 x pi / 2.
Cosine is 0.995
Cosine is 0.766
The cosine of 24 degrees is 0.913
The cosine of 60 degrees is 0.5
Cosine(42 radians) = -0.399985 Cosine(42 degrees) = 0.743146
Cosine(84 radians) = -0.680023 Cosine(84 degrees) = 0.104528
cosine(59 degrees) = 0.51504 (rounded)
The cosine of 10 degrees is 0.98480775301221. Hope I helped!
