Final answer:
To find the integrals in exercises 3-50, use integration techniques like power rule or substitution. Check your answers by taking the derivative.
Step-by-step explanation:
To find the integrals in exercises 3-50, you can use integration techniques such as power rule, substitution, or integration by parts, depending on the form of the integrals. The first step is to identify the integrals and apply the appropriate integration technique. Then, you can find the antiderivative and add the constant of integration. To check your answers by differentiation, take the derivative of the antiderivative you found and see if it matches the original function.
