it is 0because on the unit circle 270 is the negative y axis (0,1) the x coordinate is the cos value
The secant of an angle is defined as the reciprocal of the cosine of that angle. At 270 degrees, the cosine is 0, so the secant, which is 1/cos(270°), is undefined. Therefore, the secant of 270 degrees does not have a defined 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
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!
