I AM A RETIRED, AMERICAN PHYSICIAN AND MATHEMATICIAN!! I was a board certified, fellowship-trained, cardiovascular and thoracic doctor. As such, I am well trained in the sciences (biology, chemistry, physics, all medical sciences and all other undergraduate sciences). I CAN TEACH AND EXPLAIN math through calculus. WILL NEGOTIATE PRICE. I tutored math and science in college and medical school. I WILL EXPLAIN THE SUBJECTS SO THAT YOU WILL UNDERSTAND THEM IMPLICITLY, AND THEREFORE, YOU WILL NEVER HAVE TO MEMORIZE ANYTHING.
For example: "What is the value of any variable (such as X), or any rational number, raised to the zero power?" Most people think that the answer is 0, but the answer is 1. ( X^0=1 or 5^0=1)
If you are curious to know WHY this is the answer, contact me, and I will explain it in chat. This is a brief example of how I teach.
