Which of the following would be an acceptable first step in simplifying the expression (sinx) / (1 + sinx) ?. A. 1 / (cscx + sinx). B. sinx + 1. C. (sinx (1 - sinx)) / ((1 + sinx) (1 - sinx))

We are given with the function (sinx) / (1 + sinx). To simplify the equation, we multiply the denominator with its conjugate. Hence the expression becomes (sinx) (1-sin x) / (1 + sinx) (1-sin x). Then we convert the expression into (sinx) (1-sin x) / cos^2 x. Using trigonometric functions, we can then simplify the expression.
