Integration of hyperbolic function

Click For Summary
SUMMARY

The discussion focuses on the integration of the hyperbolic function, specifically the integral $\displaystyle\int x \text{sech}^2(x^2)dx$. A key hint provided is the derivative of the hyperbolic tangent function, $\frac{d}{dx} \tanh(x) = \text{sech}^2(x)$. Additionally, the derivative of $\tanh(x^2)$ is questioned, indicating a need for understanding the chain rule in differentiation of hyperbolic functions.

PREREQUISITES
  • Understanding of hyperbolic functions, specifically $\tanh(x)$ and $\text{sech}(x)$.
  • Knowledge of integration techniques involving substitution.
  • Familiarity with differentiation rules, particularly the chain rule.
  • Basic calculus concepts, including integrals and derivatives.
NEXT STEPS
  • Study the integration techniques for hyperbolic functions.
  • Learn about the chain rule in differentiation, specifically for composite functions.
  • Explore the properties and applications of hyperbolic functions in calculus.
  • Practice solving integrals involving hyperbolic functions with varying degrees of complexity.
USEFUL FOR

Students and professionals in mathematics, particularly those studying calculus and integration techniques involving hyperbolic functions.

i don't know how start. please help.

$\displaystyle\int xsech^2(x^2)dx$
 
Physics news on Phys.org
Hint :

$$\frac{d}{dx} \tanh(x)=\text{sech}^2(x)$$

What about

$$\frac{d}{dx} \tanh(x^2)$$
