`sin2 0^@sin4 0^@sin6 0^@sin8 0^@`

Prove that: \ sin 10^0sin 50^0sin 60^0sin 70^0=(sqrt(3))/(16)

Prove that: "sin"20^0"sin"40^0"sin"60^0"sin"80^0=3/(16)

Prove that: "sin"20^0"sin"40^0"sin"60^0"sin"80^0=3/(16)

Prove that: sin20^0sin40^0sin60^0sin80^0=3/(16)

Prove that: sin20^0sin40^0sin60^0sin80^0=3/(16)

sin20^(0)sin40^(0)sin60^(0)sin80^(@)=(3)/(16)

sin2x + sin4x + sin6x=0

prove that sin10^(0)+sin20^(0)+sin40^(@)+sin50^(0)=sin70^(0)+sin80^(@)

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 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
