Final answer:
Integration by parts involves using a step-by-step method to solve integrals, or using a TI-83, TI-83+, or TI-84 calculator's built-in integration feature.
Step-by-step explanation:
The first solution is a step-by-step approach, which involves using the integration by parts method to solve integrals. This method allows us to find the integral of a product of two functions by using a specific formula: ∫u dv = uv - ∫v du. We choose one function to differentiate (u) and another function to integrate (v).
The second solution involves using a function of the TI-83, TI-83+, or TI-84 calculators. These calculators have built-in integration capabilities that can solve definite and indefinite integrals. To use this method, you need to enter the function and specify the limits of integration if applicable.
To find the solution using either solution A or solution B, follow the step-by-step instructions or use the calculator's built-in integration feature.
