Verified step by step guidance

Step 1: Identify the function y = 1 - x^2 - x * cos^(-1)(x). The goal is to find its derivative with respect to x. This involves using the sum, product, and chain rules of differentiation.

Step 2: Differentiate the first term, 1, with respect to x. The derivative of a constant is 0.

Step 3: Differentiate the second term, -x^2, with respect to x. Using the power rule, the derivative of -x^2 is -2x.

Step 4: Differentiate the third term, -x * cos^(-1)(x), with respect to x. Use the product rule: if u = x and v = cos^(-1)(x), then the derivative is u'v + uv'. Here, u' = 1, v = cos^(-1)(x), and v' = -1 / sqrt(1 - x^2) (the derivative of cos^(-1)(x)).

Step 5: Combine all the derivatives from steps 2, 3, and 4. Simplify the expression to get the final derivative: -2x - cos^(-1)(x) - x / sqrt(1 - x^2).
