SUMMARY
The integral discussed is ∫ du / cos(π/4 - u). To solve this, a substitution of v = u - π/4 is recommended. After this substitution, the integral simplifies to ∫ 1/cos(x) dx, which can be evaluated using the formula ∫ 1/cos(x) dx = log_e |(1 + sin(x))/cos(x)| + C. This method effectively transforms the original problem into a more manageable form.
