Looking For A Math Tutor In Chula Vista.

I'm looking for help specifically understanding material in Calculus 2 at SDSU, with an emphasis on why the concepts work the way they do. Memorization is fine, but the best way for me to learn is finding the significance or reasoning behind a concept functioning the way it does. That aside, my main roadblock for lack of understanding in this class is the combination of trigonometry in tandem with the material.
