What is Study: Definition and 1000 Discussions

A case study involves an up-close, in-depth, and detailed examination of a particular case or cases, within a real-world context. For example, case studies in medicine may focus on an individual patient or ailment; case studies in business might cover a particular firm's strategy or a broader market; similarly, case studies in politics can range from a narrow happening over time (e.g., a specific political campaign) to an enormous undertaking (e.g., a World War).
Generally, a case study can highlight nearly any individual, group, organization, event, belief system, or action. A case study does not necessarily have to be one observation (N=1), but may include many observations (one or multiple individuals and entities across multiple time periods, all within the same case study). Research projects involving numerous cases are frequently called cross-case research, whereas a study of a single case is called within-case research.Case study research has been extensively practiced in both the social and natural sciences.

    As 𝜶 varies in ℝ, study the behaviour of this series

    ##\sum_{n=1}^\infty \frac {(sin 𝜶)^n}{2n} ## I apply the root test and i get ##\lim_{n \rightarrow +\infty} \frac {sin 𝜶}{2n^\frac 1 n} ## at this point i don't know how to treat the denominator.
