SUMMARY
The integral \(\int \frac{1}{t^4 + 16} \, dt\) presents significant challenges, particularly when attempting substitutions such as \(t^2 = 4u\) to simplify the expression. Users in the discussion highlighted the complexity of the integral, noting that it can lead to complicated results involving logarithmic and inverse tangent functions. The hint provided by dextercioby suggests factoring \(t^4 + 16\) into \((t^2 + 4)^2 - 8t^2\) and using partial fractions, but this approach also leads to complications, including imaginary numbers in the solution.
