In this video I proof the squeeze theorem using the precise definition of a limit. For further explanation and examples on the squeeze theorem and the precise definition of a limit make sure to watch the

In this video I go over the proof for the inverse trigonometry identity which is listed below in the many ways of writing inverse trigonometry: inverse sec(x) = inverse cos(1/x) arcsec(x) = arccos(1/x)

In this video I go over the substitution rule for integrals and show why it is necessary for solving integrals such as integral of 2x·sqrt(1+x2). I also go over the proof for the substitution rule in which
