Specific gravity change for my world

Ok, so this is a culmination of a few questions into one final question: am I doing this right? I am trying to figure out the gravitational difference from one end of a continent to another. There is a lot of math here, sorry.

My world exists within a spinning sphere. The distance from the equator to either pole is 12,429 miles. That means each angle of degree is (roughly) 138 miles. My continent is 400 miles, starting at the equator. That means at the the most extreme angle is 2.9, I will round up to 3.

Based on the answer by @Daron, in this question, using the graph he provided below, that's a cosine of (again, roughly) 0.991.

Which, I think, means at the weakest point of the continent, the gravity is 0.991g.

Did I do this right?

Thanks guys!
