Answer:
The answer is : Cos 4° > Cos 4 radian
Step-by-step explanation:
State the signs of cos 4 radian and cos 4 degrees.
As we know the formula of converting radian into degree.
Formula: 1 rad × 180/π
Cos 4 radian = 4 x 180 /3.14 deg = 229.3 degree
1- 4 radian lies in 3rd quadrant
2- It's sign is negative (-ve)
Cos 4 degree lies in 1st quadrant so the sign is + ve, therefore, Cos 4° is greater than Cos 4 radian.
Cos 4° > Cos 4 radian
