Answer 1

Step-by-step explanation:

Aata hai , you can search this question in Brainly,I have answered this question already when I was in 10th class .

Solution :-

given = 4sin2Acos4A* sin6A

multiply and divide by cos2A

we get,

=> 4sin2A * cos2A * cos4A * sin6A /cos2A

as we know that , sin2A = 2sinA *cosA

•°•we can also write it in such way

i.e, 2*2sin2A cos2A * cos4A * sin6A /cos2A

= 2 sin4A * cos4A * sin6A / cos2A

= sin8A* sin6A / cos2A

Now , put the the value of A = 15° or you can simplify more

Anyways I am putting the value from here

Sin 8(15°) sin6(15°) / cos2*15°

sin120° sin90° / cos30°

sin(90° + 30°)* 1 /cos30

cos30° / cos30° = 1 Answer
