Question

Among the following, a correct statement is
A) sin 30°> sin 60° B) cos 5° > cos 45º
C) tan 60° > tan 30°
D) both B. C​

Answer 1

Answer:

both b and c are correct in the question

Answer 2

Answer:

D) both B,C

Explanation:

clearly

for option

A) sin 30 = 1/2 < sin 60 = √3/2

B) hence we know value of cos is decreasing order in first quadrant.hence cos 5 is greater than cos 45.

C)tan 60 = √3 > tan 30 = 1/√3
