The value of `sin^2 4 6^0+sin^2 1 4^0+sin4 6^(@)sin1 4^(@)=`

Write the value of the expression 1-4sin10^(0)sin70^(@)2sin10^(0)

The value of 4sin 127 1/2^@ sin 97 1/2^@=

3sin6^(@)-4sin^(3)6^(0)=

The average value of sin2^@,sin4^@, sin6^@.........sin180^@ is (i) 1/90 cos1^0 (ii) 1/90 sin1^0 (iii) 1/90cot1^0 (iv) none of these

" The value of "(sin1^(0)+sin3^(0)+sin5^(0)+sin7^(0))/(cos1^(0)*cos2^(0)*sin4^(0))" is "

If cosA+cos^(2)A=1 , then find the value of sin^(12)A+3sin^(10)A+3sin^(8)A+sin^(6)A+sin^(4)A+sin^(2)A .

Evaluate: sin(2\ sin^(-1)0. 6)

The value of 3(sin1-cos1)^(4)+6(sin1+cos1)^(2)+4(sin^(6)1+cos^(6)1) is equal to
