Find the value of 5(sin100^(@)cos27^(@)+sin27^(@)cos100^(@)).

If cot(sin^(-1)sqrt(1-x^(2)))=sin(tan^(-1)(x sqrt(6))),x!=, then possible value of x is

((-1+sqrt(3)i)/(2))^(100)+((-1-sqrt(3)i)/(2))^(100)=

If sin^(100) theta - cos^(100) theta =1 , then theta is

sin^(-1){cot(sin^(-1)(sqrt((2-sqrt(3))/(4))+cos^(-1)((sqrt(12))/(4))+sec^(-1)sqrt(2))}
