SUMMARY

The discussion focuses on integrating the function M(x,y) = x + arctan(y) with respect to x. Participants confirm that since arctan(y) is a function of y and does not depend on x, it can be treated as a constant during integration. The integral is expressed as ∫ arctan(y) dx = arctan(y) * x + C, where C represents the constant of integration. This conclusion is supported by the understanding that the integration of a constant yields a linear term in x.

PREREQUISITES
  • Understanding of basic calculus concepts, specifically integration.
  • Familiarity with the arctangent function and its properties.
  • Knowledge of differential equations and their components.
  • Ability to manipulate algebraic expressions involving variables.
NEXT STEPS
  • Study integration techniques for functions of multiple variables.
  • Learn about the properties of inverse trigonometric functions, particularly arctan.
  • Explore applications of arctan in solving differential equations.
  • Investigate the concept of constants of integration in calculus.
USEFUL FOR

Students and professionals in mathematics, particularly those studying calculus and differential equations, will benefit from this discussion.

Hi,

Part of solving a differential equation involves integrating M(x,y) with respect to x, where M(x,y) = x + tan-1(y). What are the steps to integrating the arctan portion?

\int tan-1(y) dx

Thank you.

If I'm not mistaken, it should just be tan-1(y) * x
 
welcome to pf!

hi lolallday! welcome to pf! :wink:

i agree with m1ke_ :smile:

a function of y does not depend on x, so it integrates (and differentiates) as a constant

+ C :-p
