Cos 4° is + ve
Cos4° > Cos 4
Step-by-step explanation:
State the signs of cos 4 and cos4º. Which of
these two functions is greater
Cos 4
= Cos (4 * 180/π)°
= Cos(4 * 180 /3.14)°
= Cos 229.3°
= Cos(180 + 49.3)°
= - Cos49.3°
Cos4 is -ve
Cos 4° is + ve
as Cos 4 is - ve & Cos4° is + ve
=> Cos4° > Cos 4
