SUMMARY
The integral ∫u²√(a²-u²) du from 0 to a can be solved using trigonometric substitution. The suggested substitution is u = a sin(θ), which transforms the integral into a more manageable form. After applying this substitution, the integral simplifies to ∫a² sin²(θ) cos(θ) a dθ, allowing for straightforward integration. The final result can be computed by evaluating the definite integral after substituting back for u.
