Find the domain of 1/1-2sinx

Answer»

Hello! ! !

Hey dear here is your answer ___________

➖Function is f(X) = 1/(1 - 2sinx)
function is DEFINED only when 1 - 2sinx ≠ 0


➖Let 1 - 2sinx = 0
sinx = 1/2 = sinπ/3


➖we know, if sinФ = sinα then, Ф = nπ + (+1)ⁿ α
so, x = nπ + (-1)ⁿπ/3 , where n is INTEGERS


➖Hence, domain of f(x) is all real NUMBER except {nπ + (-1)ⁿπ/3}


➖e.g., domain ∈ R - {nπ + (-1)ⁿπ/3 , n∈I}
