Values of sin 30°, sin 90°, sec 60° are in ………… A) A.P.�

1.	Values of sin 30°, sin 90°, sec 60° are in ………… A) A.P. B) G.P. C) a D) (A)or(C)
Answer» Correct option is: B) G.P. Sin \(30^\circ\) = \(\frac 12\) sin \(90^\circ\) = 1 and sec \(60^\circ\) = 2 \(\because\) \(\frac 12\), 1 & 2 are in G.P \(\therefore\) sin \(30^\circ\), sin \(90^\circ\) & sec \(60^\circ\) are in G.P Correct option is: B) G.P.

Values of sin 30°, sin 90°, sec 60° are in ………… A) A.P. B) G.P. C) a D) (A)or(C)

Answer»

Correct option is: B) G.P.

Sin \(30^\circ\) = \(\frac 12\)

sin \(90^\circ\) = 1

and sec \(60^\circ\) = 2

\(\because\) \(\frac 12\), 1 & 2 are in G.P

\(\therefore\) sin \(30^\circ\), sin \(90^\circ\) & sec \(60^\circ\) are in G.P

Correct option is: B) G.P.
