SUMMARY
The forum discussion centers on solving two integral calculus problems: ∫2x^3 sin(x^2)dx and ∫x(2x-3)^(1/3)dx. The user attempted to solve the second integral using U-Substitution but received an error on their TI-89 calculator, indicating an "invalid implied multiply." The community provided feedback, confirming the user's approach to the second integral was incorrect and suggested using proper notation for clarity. The first integral remains unsolved, with the user struggling to apply substitution and integration by parts effectively.
