Thank you. You explained the approach exceptionally well.

I found this video very help...however I have a question. I understand the 0 to 2pi for horizontal tangent because of periodicity of cos. If my problem started off with y=sin7t will that change the periodicity or do i still add a 2pi to pi/2. Hope that question makes sense.

extremely helpful video. I am just wondering how you determined the last two "t" values of (5pi/4) and (7pi/4)

why did you have to add 2pi when you were solving for cosine but not when you were solving for sine

why did you use the boundaries 0 to 2 pi for only the horizontal tangent lines?
