The cosine of 10 degrees is 0.98480775301221. Hope I helped!
It is cosine*cosine*cosine.
0.5735764264 (nearest 10 decimal places).
Cosine 0 is 1
sine 10. Use the cofunction with the complementary angle.
what is the cosine of 3.14 ?
Cosine of 1 degree is about 0.999848. Cosine of 1 radian is about 0.540302.
Tangent = sine/cosine provided that cosine is non-zero. When cosine is 0, then tangent is undefined.
The inverse of the cosine is the secant.
Reciprocal of Cosine is Secant
Cosine of -90 is 0.
