Write the value of the expression `(1-4sin1 0^0sin7 0^0)/(2sin1 0^0)`

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

The value of the expression (1-4sin 10^0 sin 70^0)/(2sin 10^0 ) is- a.1/2 b. 1 c.2 d. none of these

The value of the expression (2(sin1^(0)+sin2^(0)+sin3^(0)+...+sin89^(@)))/(2(cos1^(0)+cos2^(0)+...+cos44^(0))+1) equals

The value of the expression (tan^(2)20^(0)-sin^(2)20^(@))/(tan^(2)20^(0)+sin^(2)20^(@)) is

The value of expression (2(sin1^(0)+sin2^(0)+sin3^(0)+...+sin89^(@)))/(2(cos1^(0)+cos2^(0)++cos44^(0))+1) (a) sqrt(2)(b)(1)/(sqrt(2))(c)(1)/(2)(d)0

The value of expression (2sin^(2)91^(0)-1)(2sin^(2)92^(0)-1)...(2sin^(2)180^(@)-1) is equal to 0(b)1quad (c)2^(90)(d)2^(90)-90

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

sin(2sin^(-1) 0.8)=
