`sin(17pi/3)`

Value of expression sin(pi/9)+sin((2pi)/9)+sin((3pi)/9)+...+sin((17pi)/9)=

Value of expression sin(pi/9)+sin((2pi)/9)+sin((3pi)/9)+...+sin((17pi)/9)=

Evaluate each of the following: (i) sin^(-1)(sin((13pi)/7)) (ii) sin^(-1)(sin((17pi)/8)) (iii) sin^(-1){sin(-(17pi)/8)}

(tan(35pi//6)*sin(-11pi//3)*sec(-7pi//3))/(cot(5pi//4)*"cosec"(7pi//4)*cos(17pi//6))=

sin((13pi)/3)sin((8pi)/3)+cos((2pi)/3)sin((5pi)/6)=1/2

Prove that : tan((11pi)/3)-2sin((9pi)/3)-3/4cosec^2(pi/4)+4cos^2((17pi)/6)=(3-2sqrt(3))/2

sin[cot^(-1)(cot backslash(17 pi)/(3))]

Evaluate each of the following: sin^(-1)((sin(13 pi))/(7))( ii) sin^(-1)((sin(17 pi))/(8))( iii) sin^(-1){(s in-(17 pi)/(8))}

The value of sin theta sin((pi)/(3)-theta)sin((pi)/(3)+theta) lies in [pi,theta], then pi=... and theta=...

sin((pi)/(3)+A).cos((pi)/(3)+B)-cos((pi)/(3)+A).sin((pi)/(3)+B)=...
