When calculating sin^−1 θ, defined values will always bea value from [-1, 1]a positive real number no greater than 1a value from [[−π2 , π2]a value from [0, π]
sin⁻¹θ is the inverse function of sine. Since sin(x) can only take values between 1 and -1, sin⁻¹θ will be defined for values between -1 and 1, so the answer is
