SUMMARY

The integral discussed is \(\int\frac{1}{\sqrt{12x+0.02x^2}} dx\). The recommended technique for solving this integral involves completing the square within the square root, transforming it into a form resembling \(a(x+b)^2-c\). Following this, a trigonometric substitution, specifically \(c \sec^2(u) = a(x+b)^2\), is suggested to facilitate the integration process.

PREREQUISITES
  • Understanding of integral calculus
  • Familiarity with completing the square

hey, this isn't really a homework problem but I have this integral that I can't solve cause i haven't studied techniques of integration.

Any suggesstions

First you want to complete the square inside of the square root. You'll get something like a*(x+b)^2-c. Then do a trig substitution like c*sec(u)^2=a*(x+b)^2. Try it.
