Which is larger, the cosine of 77 degrees or the sine of 77 degrees?

sin 77° > cos 77°

Step-by-step explanation:

The cosine of 77 degree,

The sine of 77 degree,

In I quadrant sine and cosine both positive.

But sine is increasing curve and cosine is decreasing curve.

The intersection of sine and cosine at 45°

sin 45° = cos 45°

After intersection, if angle is increasing the value of sine is more than cosine.

But sin 45° = cos 45°

Therefore, sin 77° > cos 77°

Hence, sine of 77 degree is larger than cosine 77 degree.

it is a reproduction.
