sin292(1)/(2)

What is the value of sin 292(1)/(2)""^@ ?

If A=340^(@), prove that 2sin((A)/(2))=-sqrt(1+sin A)+sqrt(1-sin A) and 2cos((A)/(2))=-sqrt(1+sin A)-sqrt(1-sin A)

sin^(-1)(1/2)-2sin^(-1)(1/(sqrt(2)))

sin[(pi)/(2)-sin^(-1)-1/2]

sin[(pi)/(2)-sin^(-1)(-(1)/(2))]

2sin((A)/(2))=-sqrt(1+sin A)+sqrt(1-sin A) if A=340^(@)

If f(A)=(sqrt(1+sin((A)/(2)))+sqrt(1-sin((A)/(2))))/(sqrt(1+sin((A)/(2)))-sqrt(1-sin((A)/(2))))

Evaluate: lim_(n rarr0)(1^(1/sin^(2)x)+2sin^((1)/(2sin^(2)x))+...+n^(1/sin^(2)x))^(sin^(2)x)

lim_(x rarr0)(sin^(-1)x+3x)/(tan x+2sin((1)/(2)sin^(-1)x)[3-4sin^(2)((1)/(2)sin^(-1)x)])=
