" 05.If "cos A=(3)/(4)" then the value of "sin(A)/(2)sin(5A)/(2)" is "

If cos A =3/4 then, the value of sin ""A/2sin ""(5A)/(2) is-

If cos A = 3/4 then the value of 32sin( A/2)* sin (5A/2) is_____.

If cos A=(3)/(4), then the value of 16cos^(2)((A)/(2))-32sin((A)/(2))sin(5(A)/(2)) is

If cos A=3/4 then the value of 2 sin(A/2) sin((5A)/2) is.............. A) (sqrt11)/(16) B) -(sqrt11)/(16) C) (11)/(16) D) -(11)/(16)

If cos A = 3//4 . then what is the value of sin ((A)/(2))sin((3A)/(2)) ?

cos A =(3)/4 implies 32 sin""((A)/(2)) sin""((5A)/(2))=

If cos A+cos^(2)A=1, find the value of sin^(2)A+sin^(4)A
