Derivative of \( \displaystyle \operatorname{asin}{\left(\sqrt{x} \right)} \)

Problem 2.481 · hard

Differentiate \( \displaystyle f(x) = \operatorname{asin}{\left(\sqrt{x} \right)} \).
  1. \[ \frac{d}{d x} \operatorname{asin}{\left(\sqrt{x} \right)} \]
    derivativeStart with the derivative of the function.✓ Proved
  2. \[ = \frac{\frac{d}{d x} \sqrt{x}}{\sqrt{1 - x}} \]
    chain algebraApply the chain rule to the arcsine function. Simplify the term inside the square root.✓ Proved
  3. \[ = \frac{1}{2 \sqrt{x} \sqrt{1 - x}} \]
    derivative algebraDifferentiate the inner square root function. Combine the terms into a single fraction.✓ Proved
  4. \[ = \frac{1}{2 \sqrt{x \left(1 - x\right)}} \]
    simplifySimplify the expression by bringing x into the square root.≈ Checked numerically
Answer \( \frac{1}{2 \sqrt{x} \sqrt{1 - x}} \)

✓ Nihil obstat Lines: 5 proved, 2 checked numerically. The answer was also checked a second way, without looking at the solution. Reviewers found nothing wrong with the explanation.

Proved: SymPy reduced the difference between the two sides to zero. Checked independently: a separate method, named above, confirmed it. Checked numerically: the two sides agree at every sampled point, which is evidence, not proof. Reviewed: a model or a person read it; that is all a sentence can have. Solution by gemma4:26b, checked 2026-09-26 with SymPy 1.14.0.
