SUMMARY

In mathematical physics, alpha (α) and theta (θ) can represent the same angle or different angles depending on the context. For example, in the equation Vi = vo(sin)(θ) and Vi = vo(sin)(α), both symbols can denote an angle, but they may also be defined differently based on the specific problem. It is common to relate these angles, such as defining α as half of θ (α = θ/2). The choice of symbol is often arbitrary and determined by the conventions used in specific scenarios.

I was wondering in terms of a mathematical approach to physics, whether alpha and theta represent the same known or unknown angle in the triangles.



Ex.. Vi = vo(sin)(theta)

or

Vi = vo(sin)(alpha)

It represent whatever we define it to represent. Sometimes alpha is used, other times theta. Sometimes just one is used, and other times they are both used to represent different angles. Sometimes they are related in a way such as for instance letting alpha=theta/2.
 
Nice thanks man
