SUMMARY

The derivative of the function y = arctan(x + sqrt(1+x^2)) can be found using the chain rule. The derivative of arctan(u) is 1/(1+u^2) multiplied by the derivative of u, where u = x + sqrt(1+x^2). After applying the chain rule and simplifying, the final expression for the derivative is established. This method effectively combines differentiation techniques with algebraic simplification.

PREREQUISITES
  • Understanding of the chain rule in calculus
  • Knowledge of the derivative of the arctan function
  • Familiarity with algebraic simplification techniques
  • Basic comprehension of functions involving square roots
NEXT STEPS
  • Study the chain rule in depth with examples
  • Learn about derivatives of inverse trigonometric functions
  • Practice algebraic simplification of derivatives
  • Explore applications of the arctan function in calculus
USEFUL FOR

Students studying calculus, particularly those focusing on differentiation techniques, and anyone seeking to understand the properties of inverse trigonometric functions.

Homework Statement



Find the derivative of the function. Simplify if possible.

y = arctan (x + sqrt(1+x^2))

Homework Equations



I know there's something like... y = arctan(x) = ( x = tan(y) )

I'm not sure how to manipulate it...

The Attempt at a Solution



I'm not really sure how to start, any help would be greatly appreciated.

Thanks!

You probably know the derivative of arctan. If so, just differentiate it using the chain rule and do some algebra to simplify it.
