SUMMARY

The derivative of the function arcsin(4x+2) is calculated as 4 / (√(1 - (4x + 2)²)). The initial confusion regarding the expression arose from a typographical error where (4x - 2) was mistakenly used instead of the correct (4x + 2). Tools such as Wolfram Integrals and Calc101 can be utilized for verification of derivatives and exploring alternative methods of simplification.

PREREQUISITES
  • Understanding of calculus concepts, specifically derivatives.
  • Familiarity with the arcsine function and its properties.
  • Knowledge of the chain rule in differentiation.
  • Basic skills in using online mathematical tools for verification.
NEXT STEPS
  • Study the chain rule in calculus for better understanding of derivative calculations.
  • Explore the properties of inverse trigonometric functions, particularly arcsin.
  • Learn how to use Wolfram Alpha for checking derivatives and integrals.
  • Investigate common mistakes in derivative calculations and how to avoid them.
USEFUL FOR

Students studying calculus, particularly those learning about derivatives of inverse trigonometric functions, and anyone seeking to verify their mathematical solutions using online tools.

What is the derivative of arcsin(4x+2)?


Homework Equations





The Attempt at a Solution


I just want to check that I'm doing this correctly; my teacher didn't give me any examples to try.

I get 4 / (\sqrt{1-(4x-2)^2})

Is that right?
EDIT: Just realized I posted this in precal math, sorry! =(

Why do you have (4x-2) in the radical? Typo, right? Otherwise, it's fine.
 
Whoops, it's supposed to say 4x+2. It's still supposed to be in the radical, though.
 
Then it's just fine.
