What is the antiderivative of sinx

The video tutorial discusses the process of finding antiderivatives, specifically focusing on the function cosine of X. It highlights common mistakes, such as assuming the antiderivative without verification, and emphasizes the importance of checking work by taking derivatives to ensure correctness. The tutorial also provides advice on correcting errors, like adding a negative sign to the antiderivative, and encourages students to review their work, especially when working quickly.
