Final answer:
To find the general indefinite integral, apply the rules of integration and include the constant of integration (c).
Step-by-step explanation:
The given question is asking for the indefinite integral with respect to different variables: x, t, s, and u. To find the integral, we need to use the rules of integration. Since the question does not provide a specific function to integrate, we cannot provide a detailed step-by-step explanation. However, the process of finding the indefinite integral involves applying the power rule, the chain rule, and other integration techniques, depending on the specific function. Each integral will have its own unique solution, and the constant of integration (c) should be included for each result.
