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
cosine 45° = √2/2 (Square root of 2 over 2)
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.
