Answer 1

@ranga @hartnn

Answer 2

use the double angle formula
\(2\sin x\cos x = \sin 2x \)

Answer 3

But what values nothing for 15 degrees not like our 30 or 60 values ?

Answer 4

no, 15 degree is not a standard angle

Answer 5

\(2\sin15(\cos15) = \sin (2 \times 15) =...\)

Answer 6

30

Answer 7

sin 2(15)=0.5

Answer 8

yes
and sin 30 is indeed 0.5 :)

Answer 9

\[\frac{1}{2}\]

Answer 10

any doubts ?

Answer 11

no,sir
