Substitution in Indefinite Integral

Click For Summary
SUMMARY

The discussion focuses on the application of substitution in indefinite integrals, specifically using the integral of \(\frac{1}{1 + u^{2}}\). The solution involves taking constants out of the integral, leading to the result \(\frac{1}{2}\tan^{-1}(u) + C\) where \(u = x^{2}\). The final expression simplifies to \(\frac{1}{2}\tan^{-1}(x^{2}) + C\), demonstrating the effectiveness of substitution in solving integrals.

Take the constants out of the integral and solve,

\frac{1}{2}\int \frac{du}{1 + u^{2}} = \frac{1}{2}tan^{-1}(u) + C

Since,

u = x^{2}

Then,

\frac{1}{2}tan^{-1}(u) + C = \frac{1}{2}tan^{-1}(x^{2}) + C
 
Oh snap, that was easy.
Thank you!
