Evaluate: ∫ 1 X 2 + 16 D X - Mathematics

Question

Evaluate: \[\int\frac{1}{x^2 + 16}\text{ dx }\]

Sum

Solution

\[\int\frac{1}{x^2 + 16}dx = \int\frac{1}{x^2 + 4^2}dx\]
\[ = \frac{1}{4} \tan^{- 1} \frac{x}{4} + c\]
\[\text{ Hence,} \int\frac{1}{x^2 + 16}dx = \frac{1}{4} \tan^{- 1} \frac{x}{4} + c\]
