Derivative of \( \displaystyle \operatorname{asin}{\left(10 x - 6 \right)} \)
Problem 2.565 · easy
Differentiate \( \displaystyle f(x) = \operatorname{asin}{\left(10 x - 6 \right)} \).
- \[ \frac{d}{d x} \operatorname{asin}{\left(10 x - 6 \right)} \]derivativeStart with the derivative of the function.✓ Proved
- \[ = \frac{\frac{d}{d x} \left(10 x - 6\right)}{\sqrt{1 - \left(10 x - 6\right)^{2}}} \]chainApply the chain rule for the arcsine function.✓ Proved
- \[ = \frac{- \frac{d}{d x} 6 + \frac{d}{d x} 10 x}{\sqrt{1 - \left(10 x - 6\right)^{2}}} \]sumDifferentiate the terms inside the parentheses separately.✓ Proved
- \[ = \frac{10}{\sqrt{1 - \left(10 x - 6\right)^{2}}} \]constant algebraThe derivative of 10*x is 10 and the derivative of 6 is 0. Simplify the expression.✓ Proved
- \[ = \frac{10}{\sqrt{- 100 x^{2} + 120 x - 35}} \]algebra simplifyExpand the squared term. Simplify the expression under the square root.✓ Proved
Answer \( \frac{10}{\sqrt{1 - \left(10 x - 6\right)^{2}}} \)
✓ Nihil obstat Every line of this solution was proved by the computer algebra system SymPy. 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.
