How to find the Arc Length and Sector Area of Circles

[@lnribeiro1]

Could you think of doing something on integrals, complex numbers and/or other aspects, applied to areas such as physics? Probabilities stuff would also be interesting, namely applied to demographics, election polls, etc. Concerning this particular video, very interesting. Keep up the good work

Thanks. Yes I’ll give that some thought.
