In summary, the formula for deriving arcsin(1 - 2 e ^-t) is arcsin(x) = -i * ln(ix + sqrt(1 - x^2)), where x is the input value of 1 - 2 e ^-t. The purpose of deriving arcsin(1 - 2 e ^-t) is to find the angle whose sine is equal to the input value. The steps for deriving arcsin(1 - 2 e ^-t) involve substituting the input value into the formula and simplifying the expression. The domain of arcsin(1 - 2 e ^-t) is all real numbers between -1 and 1, and the range is between -
