cos(55) = 0.022126756261956
You cannot. The cosine of 30 degrees is an irrational number.
Cosine(42 radians) = -0.399985 Cosine(42 degrees) = 0.743146
The cosine of 10 degrees is 0.98480775301221. Hope I helped!
The cosine of 0.57 degrees is 0.999951. The cosine of 0.57 radians is 0.841901
cos(35)sin(55)+sin(35)cos(55) If we rewrite this switching the first and second terms we get: sin(35)cos(55)+cos(35)sin(55) which is a more common form of the sin sum and difference formulas. Thus this is equal to sin(90) and sin(90)=1
The cosine of 90 degrees is zero.
The cosine of 8 degrees is 0.99026806874157031508377486734485
cos(55) = 0.022126756261956
Cosine is 0.995
Cosine is 0.766
The cosine of 60 degrees is 0.5
The cosine of 24 degrees is 0.913
You cannot. The cosine of 30 degrees is an irrational number.
If you have a suitable calculator, you can find it directly. It is also the same as the sine of 55 degrees, which can be looked up in many tables.
Cosine(42 radians) = -0.399985 Cosine(42 degrees) = 0.743146
Cosine(84 radians) = -0.680023 Cosine(84 degrees) = 0.104528
