Question

Порівняйте: 1.cos70° i sin0° 2.sin100 i sin 80°

Answer 1

Ответ:

1.cos70° > sin0°

2.sin100 < sin 80

Answer 2

1. cos(70°) and sin(0°):

   • cos(70°) is the cosine of 70 degrees, which is equal to approximately 0.3420.
   • sin(0°) is the sine of 0 degrees, which is equal to 0.

2. sin(100°) and sin(80°):

   • sin(100°) is the sine of 100 degrees, which is equal to approximately 0.9848.
   • sin(80°) is the sine of 80 degrees, which is equal to approximately 0.9848.

So, the comparisons are as follows:

1. cos(70°) is smaller than sin(0°).
2. sin(100°) is equal to sin(80°).
