cosec(13 pi/12)

Compute cosec (13pi//12)

What is the value of cosec (13pi//12) ?

If sin^-1(x/13) + cosec^-1(13/12) = pi/2 then the value of x is

The exact value of cos((2pi)/28)cosec((3pi)/28)+cos((6pi)/28)cosec((9pi)/28)+cos((18pi)/28)cosec((27pi)/28)

If cosec . (pi)/(32)+ cosec. (pi)/(16)+ cosec. (pi)/(8)+ cosec. (pi)/(4)+ cosec. (pi)/(2)= cot. (pi)/(k) , then the value of k is

If cosec . (pi)/(32)+ cosec. (pi)/(16)+ cosec. (pi)/(8)+ cosec. (pi)/(4)+ cosec. (pi)/(2)= cot. (pi)/(k) , then the value of k is

If cosec . (pi)/(32)+ cosec. (pi)/(16)+ cosec. (pi)/(8)+ cosec. (pi)/(4)+ cosec. (pi)/(2)= cot. (pi)/(k) , then the value of k is

The value of the expression 1+"cosec"(pi)/(4)+"cosec"(pi)/(8)+"cosec"(pi)/(16) is equal to

The value of the expression 1+"cosec"(pi)/(4)+"cosec"(pi)/(8)+"cosec"(pi)/(16) is equal to

sec A=cosec B=(13)/(12) then (A+B)=
